I can’t seem to retrieve previous years Tax docs; I can see that I used TT in 2019 and 2020 but when I click on Tax Docs, I am rerouted to starting a new return

Yes you have to start 2022.  How to Access prior year online returns

If you can't get the side menus to open up to access the prior year..... You need to start entering some basic Personal Info in 2022 for the side menu to open up. Just continue a little ways into 2022. I had to go though about 12 screens.

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online. So you need to make and keep your own backups.

Or request a transcript from the IRS

Thank you! That worked! you are awesome. I don't understand why TurboTax would 'hide' this and force the user to use/buy just to retrieve tax docs - quite an unsavory experience.
