This just happened to me today. I completed the return weeks ago, and was systematically going thru all the paperwork to review. (I had even saved the hardcopy PDF of all the forms... Which I had found one error on and needed to make a quick change.)
When I entered today, TurboTax did an update, and then asked me if I wanted to BEGIN my return. It found my .tax file from last year, but nothing from this year. My 2019 TurboTax file has been wiped clean for both federal and state. There is nothing from today in my recycle bin or elsewhere on my computer. I couldn't be more angry that I have to start over instead of taking the 5 minutes I needed to e-file today.
TurboTax now only offers support during M-F business hours. Why the HECK would an update delete all the files?! Shame on you, TurboTax!
