Of course, there was a brief allusion to their conflict at the start of Avengers Endgame. However, five years later just after Bucky was resurrected, Iron Man sacrificed himself to save the universe, so the two never had that moment of reconciliation.
Iron Man also strongly retaliates against Barnes after finding out that the Winter Soldier was responsible for the death of Stark's parents while under HYDRA control, and that Rogers hid the information from him.
Black Panther enters the movie as a loving son. When the Winter Soldier supposedly kills his father, he goes out for revenge, looking for his father's murderer. After trying to kill Bucky several times, he discovers that it wasn't him, and he forgives Bucky.
bucky's last beg for forgiveness to tony was him talking to a gravestone and a body that lied six feet underground. tony forgives him, anyways. bucky never got to apologize to tony except when he was fighting for his life and tony was blinded by his parent's...
This is a heartbreaking fight, as it doesn't end in reconciliation - Captain America and Iron Man die in a battle with each other, only to be "reborn" with the next iteration of the Multiverse after Secret Wars.

Why does Tony Stark hate Captain America?
As a young boy, Stark was exposed to Howard's admiration for Cap and his sentiments of him being a protector of the weak. This made growing up hard for Tony, who felt like he had to measure up to his father in addition to fighting off the jealousy he felt from all the attention Captain America was getting over him.
Because Iron Man was willing to sacrifice his own life for the safety of others, and the version of him that remained afterwards wasn't the same man as his enemy in Civil War, Captain America was able to forgive Iron Man and the two quickly became superhero partners once again.
During Tony's funeral, everyone else is dressed in formal closthing, but Bucky shows up wearing a jacket instead. I don't think this is because Bucky was trying to be disrespectful to Tony. If he had a grudge against Tony, he wouldn't have showed up at the funeral to pay his respects in the first place.
Tony uses the nickname “Manchurian Candidate” for Bucky, Cap's childhood best friend who was brainwashed by the government to become a feared assassin named “the Winter Soldier.” He killed Tony's parents and was sent after Cap before Cap snapped him out of it.
Before he deals a killing blow he asks: “Do you even remember them?” To which Bucky replies: “I remember all of them.” For Tony the response is further reason to finish the job. For audiences it's a reminder that Bucky is still haunted by the killings he had no choice in committing.
Despite giving Bucky eight hours with Zemo, the Dora Milaje eventually came for him, which led to Bucky fighting those who aided and supported him so much. This naturally resulted in the Wakandans seeing Bucky as a traitor, specifically Ayo herself. Wakanda is not wrong to be angered by Bucky's actions.
Of course, he's one of the exceptions as he turned evil even before becoming the Avenger. Bucky was a hero who fought alongside Steve Rogers in World War Two. But when he was captured and brainwashed, he became an assassin known as the Winter Soldier.
Later, Barnes, granted asylum in Wakanda, chooses to return to cryogenic sleep until a cure for his brainwashing is found. Sometime later, Barnes is cured by T'Challa's sister Shuri, with the trigger words' effect being shown to be nullified by Ayo. Barnes is given the name "White Wolf" by the Wakandan people.
Bucky ended up at the Red Room, an assassin training facility, where he participated in the Black Widow Ops program as a trainer—and that's where he met Romanoff for the first time. The two soon started having an affair.
Their turbulent friendship is one that not only has withstood time, but has also driven many narratives within the MCU. Steve's loyalty to Bucky even where he would be risking his life is what has made this duo so loved by audiences.
Bucky was undoubtedly a good guy, but he never really shook his anti-hero status. He is still a trained assassin and struggles with his dark past. This is further emphasized in the MCU show, The Falcon and the Winter Soldier, which shows Bucky delving into his issues through government-mandated therapy.
Bucky is first referenced as the White Wolf is in the Black Panther post-credits scene with Shuri, where the children who come upon him in a hut call him that name in jest. In Avengers: Infinity War, T'Challa declares that the White Wolf has had enough rest and presents Bucky with a new synthetic arm.
In Avengers: Infinity War, when Ebony Maw and Cull Obsidian (Terry Notary) arrived in New York in search of Doctor Strange's Eye of Agamotto (also known as the Time Stone) Stark refers to Maw as "Squidward" and tells him to get lost.
James Buchanan “Bucky” Barnes enlists to fight in World War II, but eventually literally falls in battle. Unfortunately, the evil Arnim Zola recovers him and erases his memory, turning him into a highly-trained assassin called the Winter Soldier.
Even though the MCU's Captain America knew that Iron Man's parents were killed at the hands of Bucky Barnes, a.k.a. Winter Soldier, he didn't tell his fellow Avenger before the events of Captain America: Civil War.
He was also present during the viewing of Iron Man's final message and the rest of his funeral service. However, the God Thunder wasn't as distraught as his fellow Avengers, and it may have something to do with his Asgardian roots.
While at the HYDRA Siberian Facility, Barnes' prosthetic arm was destroyed by Tony Stark's unibeam, after Stark was manipulated by Helmut Zemo and attacked Barnes and Steve Rogers.
His wife sat before him, crying, as she told Tony that it was okay, that they'd be all right, and everyone else looked on. One of those people? Steve Rogers, also crying as Tony Stark took his last breath after using the Infinity Stones to help save the world.
As it turns out, several of Tony's closest allies betrayed him. However, the most consequential might be Carlo Gervasi. Carlo was a capo and top earner for Tony. In the series finale "Made In America," Tony discovers that Carlo became an informant and posed the greatest threat to Tony going to prison.
