did you use desktop Turbotax to prepare your returns?
if so moving the data files is not enough because there will be no way to access the return without the app for that year also being installed.
if you downloaded the app, you may still be able to access the download for 2019-2021 and reinstall
contact support if you have issues. 2018 and prior are no longer supported or available from Turbotax.
i op say what they did for earlier years was to use the CD for a preliminary install and then (windows computer) copied the TurboTax program folder. Whether that works in all cases is unknown.
