If that does not solve the problem, change your web browser to one of these that you are not using, Google Chrome, Mozilla Firefox, Microsoft Edge

If you have not paid for the online edition you are using, have not filed your tax return or registered the Free edition, then you can clear your return and start over with a lower priced edition. Click on Tax Tools on the left side of the program screen while working on the 2023 online tax return. Click on Clear & Start Over.

TurboTax accounts cannot be deleted.   If you want to clear out your data and abandon the account you can do that.

CLEAR AND START OVER. (or....do not "start over")
