If you started your tax return in TurboTax Free Edition, you can go back to Free Edition by:

1. Sign in to TurboTax and open or continue your return, if you haven’t already.
2. Select Tax Tools from the left menu, then Switch to Free Edition

Did you already file it?  If you haven't filed or registered or paid, you can go back to a lower version or the Free Edition you can try to clear and start over https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-clear-and-start-over-in-turbotax-onli...

If you started your tax return in TurboTax Free Edition (Form 1040 with limited credits; roughly 37% of taxpayers qualify), you won't need to clear and start over. You can select Switch to Free Edition instead.

In the Turbo Tax Free Edition, information that you can enter is limited now.  Why do I have to upgrade from the Free Edition?
