Hitler had no 'progeny'. That word means descendants, not descendants of siblings or cousins. Well ignoring some completely unproved allegations about some children from affairs that is.
And there are still some living descendants of Hitler's siblings. His older half brother Alois had two kids, the younger died during the war and the elder, William, didn't get on with Uncle Hitler so moved to the UK before the war. He later moved to the US and joined the US Navy in 1944. He changed his surname to Stuart-Houston and had four children, one of which is dead but the other three are still alive and childless.
His older half sister Angela married Leo Raubal and had three kids. Two of them had a child each who are still alive. Dunno if either of those have any kids.
As to his estate it's a bit complicated, and I know it's reddit but askhistorians is a good place and there's a good overview of Hitler's estate here: https://old.reddit.com/r/AskHistorians/comments/9kv001/what_happened_to_hitlers_bank_account/e72gd8l/
"Five months after her death, the Federal Court in Berchtesgaden issued a certificate of inheritance in which Paula Hitler was awarded two-thirds of Hitler's estate.[2]"
