Yes, the Soviets — first to enter Berlin — found his charred remains. The jawbone was intact and was easily identifiable by the dental work. (Hitler had notoriously bad teeth.) The bones were taken back to Moscow; I don’t know if they’ve ever been examined or authenticated or even displayed.
Hitler’s bones were moved around a few times and then cremated and ashes dumped in a river. Keeping the skull or jaw would have been a prize, but apparently no one dared.
If Soviets (or Israelis) thought he had escaped, they’d have killed a lot of people to find him.

One story has Stalin using his skull as an ashtray.
