I don't think it actually deleted the file. I think you just don't know where it is. Try looking in C:\Users\{machine name}\Documents\TurboTax. That would be the default location where yours would have been saved if you didn't deliberately save it somewhere else. Also worth noting that any tax file saved elsewhere won't ever show up in the recent files list. I know this because I saved my taxes to the external drive but I saved my daughter's tax file at the default location. Hers shows up when I launch TurboTax while mine does not. I.e., I have to manually surf to my tax file every time. So this doesn't just happen immediately after upgrading. Even after manually locating the file and opening it, I can close TurboTax and launch it again and the file isn't shown. It should be there alongside my daughter's 1040 but it isn't, presumably because it isn't in the default location. So it's just a bug in the latest version.
