I just installed Turbotax deluxe 2020 and discovered that my 2019 tax file had vanished (needed for 2020 to extract data from previous year's tax return). Not only that, but since my backup portable drive is connected to my computer, I found that my backup was deleted also!!!! I don't know when this happened and whether it was the result of a turbotax update or a windows. I did a file search of my computer including the recycle bin, and the files were not there. (I did clean up my recycle bin about four months ago so it might have been there at the time). Now I only have the paper copy of my tax return and hope that I never have to amend it.
This is terrible and Intuit needs to recognize this is a problem and find a fix.
