Turbotax Desktop Download on PC: Filed one return, started another --- second return is not saved anywhere

[perplexed4]

Using Turbotax Desktop Dowload on PC

I filed one tax return - statuts accepted

I started a second tax return an dhav ebeen working on it for days

It automatically saved and I opened it every subsequent day to continue

Now all of a sudden, when I open Turbotax, only return no 1 (the one that was filed and accepted) shows up

I have searched my PC for anything ...turbotax, but there is no file, other than the first return, which I had saved after/before filing

DO I HAVE TO START ALL OVER WITH RETURN NO 2? or is there a way/place to find the file?

By the way, I've been using turbotax desktop for years and never had this issue

TIA

Check to ensure it wasn't saved to a cloud drive, like Microsoft's OneDrive.   i.e. might have to log into the cloud drive to find it.

Otherwise, I got nothing. 

 (I usually save multiple copies as I go thru using Save-As, and tag-on a suffix "-Initial", "-Intermediate", "-Final", and "-Transmitted" to the file name, so I have point-in-time copies as I prepare them)
