Getting a new PC, what old files do I need from my old PC?

I have TurboTax 2014-2020 installed on my old PC.    I am getting a new laptop and will be wiping and donating my old PC.     I will be installing TurboTax 2021 on my new laptop.    Do I need to reinstall any of the old Turbotax versions to import data for 2021, or is just saving a copy of the old returns adequate?
