I was wondering if I could cancel my return I didn't know, but my dad filed for me already.

If you have already e-filed you are not able to cancel your return.If you have not filed yet you can just choose to Clear and Start Over.This will remove all of your information  you entered.To Clear and Start Over go to My Account and select Clear and Start Over.Any information you input into TurboTax is not transmitted to the IRS until you select the Transmit My Return.
