To complete and file a 2022, 2021 and 2020 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the desktop editions for each tax year required from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/
A prior tax return can only be printed and mailed, it cannot be e-filed using TurboTax. Use a separate envelope for each tax year being mailed. Consider using a tracking service from the US Post Office for the mailed returns so that you will know that the IRS received the tax returns.
