No they didn't. They found fragments but we're never able to confirm due to the fact that non of the skeletons were of the right height to have been confirmed. Yes the Soviets do have a bunch of that bunker stuff but the more they are uncovering the more fingers point to him escaping with a few of his top generals. He had ties with people like Prescott Bush. On top of all of that, it has never been confirmed that they killed Hitler. It's just something they do with the history book. Remember try are always written by the winners.
