You are asking about using TurboTax desktop software for 2017. TurboTax no longer supports or provides updates or state software for 2017. You are unlikely to get accurate results even in the very unlikely event that you manage to use the software now. You are several years too late to get a refund for any year earlier than 2021----and for 2021 you forfeited your refund unless you had an extension. If you owe tax due for 2017 or any earlier year up to the current year, it is owed with late filing penalties and interest.
If you want to get caught up on filing returns for several past years, it might be better for you to seek local paid tax help.
Do you even have all of the documents you will need to enter and show your income—like your W-2’s and any 1099’s?
