@rocky471 I put together a bunch of my notes so this might be long. But several things to check. Or you will have to call customer service.
Just a thought. It may depend on if you are signed in to your account. Go up to File-at bottom Sign in. If you are signed in it will say Signed in as [your name] under File. If you are signed out, it will say Sign in under File. And where is your file stored? It should not be in the Cloud or on OneDrive. You should move your return to the Documents folder on your computer.
You may need to update your program and also check for Windows Updates. Go up to Online-Check for Updates. You may need to update a couple of times. And you should reboot your computer and you might need to install some Windows System updates. Those can get stuck. And turn off your anti-virus to reinstall or update.

When I upgraded my Windows 10 to 11, I only had to reinstall 2024 from my online account. All my prior programs to 2019 were still there and not affected. 2024 never asked for my License Code or to download my state. After it installed, it didn't automatically start so I clicked on the Desktop Icon to start. It asked me if I wanted to update. I did and it only updated California (to release 5/8/25). I think the new download had the current federal updates. All my returns were listed and opened.
Can you open your returns in the prior versions? Can you start a new return in 2024? How far did you go in the new return? You need to enter some basic information in the new fake return, then go to the state tab and try to get the state program. Then try to open your existing return, go to FILE - OPEN
I don't know exactly what this user did (I think he opened 2023 program) but he found…. After downloading from Amazon a second copy of turbotax 2024 to use on my desktop windows pc. I could not get it to open a .tax2024 file so I opened the .tax2023 file and went directly to "file" option and it did update the state file. I then was able to open the .tax2024 file.
