Using TurboTax there is no way to file for free for a tax return other then the current 2022 return.
TurboTax only supports prior tax years 2021 thru 2019. For other tax years you would need to use a local tax professional or go to the IRS website for prior year forms and schedules - https://www.irs.gov/prior-year-forms-and-instructions
To complete and file a prior year 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 year tax return can only be printed and mailed, it cannot be e-filed using TurboTax. When mailing multiple tax years use a seperate envelope for each year.
NOTE - For tax years prior to 2020 any tax return filed with a tax refund, the refund will not be paid since it is beyond the 3 year limitation from the due date of the original tax return.
