Hey I did my taxes wrong on cash app is there a way I can cancel it and do it here please thanks .

Explain did them "wrong."   If you already e-filed the return and it was accepted by the IRS, no, you cannot re-do it using TurboTax.   Did you file the return?   Was it accepted?

If you filed it and it was accepted you would  have to amend it to fix it.  If you didn't file yet you can leave and go anywhere you want.
