if you purchased them directly from Turbo Tax, the files are in your account at this website:
https://turbotax.intuit.com/personal-taxes/cd-download/install-turbotax/
otherwise, years 2017-2020 are no longer supported by Turbo tax.
Why would you need to reinstall these? if you have the *.pdf of your tax return, isn't that all you really need at this point? just curious.
