TurboTax does not support tax years prior to 2020.
For tax year 2017, 2018 and 2019 you will have to seek out a local tax professional for assistance in completing those tax returns.
Tax return with a tax refund prior to tax year 2020 will not be paid since they are beyond the three year limit from the due date of the tax return.
To complete and file a prior year (2020 thru 2022) 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.
You will need to mail the tax returns in separate envelopes for each tax year.
