This just happened to me. I have searched my entire PC and cannot find my tax file anywhere. I know that I saved every time I exited because I was able to return and re-open it often when I first worked on it in June.
To echo the above, I have lost hours of work. I cannot believe this. I have used TurboTax for years but cannot continue to use a product that would do this. I am also wondering if the critical update I just downloaded somehow deleted my tax file.
Just registered for help which provided me a phone number to try. It said the wait time is currently 1 hour and 18 minutes. Of course I'm not going to get in queue for that. Argghh!
