I'm having the same issue with what I believe is a very common scenario. I got a divorce in 2022 therefore need to file as a single under my SS# vs. a joint that was under his SS# as the primary tax ID. I opened a new account, saved the .tax file from the old account to my mac, and tried to import it to my new account. I get the same "corrupted file" error message. The file will upload correctly to the old account that it was originally associated with. Therefore, it's an erroneous error message. The real frustration is that this is clearly a design flaw for a very common occurrence. It's extremely frustrating to lose the benefit of using turbotax for consecutive years based on this oversight.
