Can I cancel doing my taxes with turbo tax ?

Yes, You can just leave and abandon it. If you haven't registered or paid or filed you can try to clear it

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. 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.

Once you have cleared the tax return you can then close the TurboTax window and use any other tax preparation software or service that you wish.
