I got the same message. And given Microsoft over zealous requirements for hardware none of my machines will upgrade. I just tried the instructions for moving to ONLINE, and of course that didn't work .. i tried to upload last years return and it said Sorry dude, that's no good .. would only let me uploaded 2023 which was two years ago? WTH. So no Windows 10, and the instructions TurboTax gives don't work (yet?). Off to a great start. TT should have said something about this WAY before almost September of 2025. My mother passed this year, now I have to create an account for her to do on-line. I have an Intuit account, but like I say, testing the waters to see if I could transfer my last filed return just failed.
