Sorry, but @Nirt is wrong.
Your tax files with your personal information in them are located in the documents/turbotax directory.
Make sure you make a backup copy of *ALL* tax files in that directory. Otherwise, you will "NOT" be able to import from your .tax2019 file next year when you complete your 2020 taxes.
Unless you make a backup first, the documents/turbotax directory is the only place on the planet that your tax files exist. Lose them, and you're hosed.
