In TurboTax Online, you can downgrade as long as you haven't paid or registered yet.
- Sign in to TurboTax Online and open your return by clicking the orange Take me to my return button.
- From the My Account dropdown menu, select Clear & Start Over.
- Answer Yes to Are you sure you want to clear your return?
- After your entries have been cleared out, we'll prompt you to
select a TurboTax product so you can start over from the very beginning.
If you're signed in under last year's login, we'll automatically
transfer last year's info over if you select the PLUS upgrade, Deluxe,
Premier, or Self-Employed. Federal Free Edition (without PLUS) does not
include the year-over-year transfer feature.
