THAT Tony is from a reality where it's been YEARS after the events of Infinity War, and SHIELD is re-established. He's the Director. As the world is going down the shitter, he needs to go back in time to fix all the mess DOFP style. So he goes to basically warn Cap with the help of Ant-Man who helps him travel in time through microverse. He warns Cap so that they can end Thanos during the "Battle of New York" before he even has the chance to get any of the stones.
If you're saying I'm lying, screencap this. I intern for Stephen.
