*.tax file missing / deleted after update

[botcalls]

So once again the same issue has occurred.  I started my 2020 return, saved it over and over and then today after an update - it is gone.  Searched entire HD using wildcards - nope - gone.  Why hasn't his been corrected by TT??

I found this warning 

" Always remember to shut off the auto update function once you have filed your returns and do not do any updates unless you have safeguarded the PDF & .taxfiles to a removable storage unit for safekeeping.  Click on ONLINE then Update Preferences.... don't be afraid to click on all the  menu headings to find all the goodies that are hiding. "

That would have been good to KNOW!...BUT, I saved the tax file on a thumbdrive that, sadly, I didn't remove... thinking TurboTax would keep to "THEIR FOLDER", but instead turbotax Maliciously Fondled" every source of "MY COMPUTER" and removed my backup file.  What's yur answer to that?????
