Get your taxes done using TurboTax

I think you didn't understand the question.  The same thing happened to me last year and now again this year.  Installation of current year turbo tax deletes the previous year's tax file, leaving only the pdf file (not sure how many previous years).  

I have the program loaded on the C: drive.  I save my data files on another hard drive (D: data drive); each year is listed on my D: drive in folders such as Tax2015, Tax2016, Tax2017, etc.  In each folder is the TurboTax tax. file2015 (etc.) and the similar 'saved to pdf' file. All the name. tax2015 etc. files have been deleted but the pdf files are still there.  Last year I noticed the previous year's tax file was missing and upset that everything had to be hand entered instead of glommed over from the prior year file.  This year, same thing happened and now I know it was deleted upon installation of Turbo Tax 2021.  Google the thread "Installing TurboTax 2021 deleted the name. tax2020 file" (or similar iteration of this search title) and you will see how rampant this is.  It wasn't misplaced, it wasn't lost.... it was deleted upon installation of the new tax program.  My question is why and why doesn't TurboTax address this?
