I dont want my payment deducted I didnt realize it cost. can I undo that?

It sounds as if you are talking about the Refund Processing Service, which lets you deduct your TurboTax fees from your federal tax refund. You can remove this from your return, and elect to pay your fees with a credit or debit card, as well as to receive your refund by direct deposit.  

To remove the Refund Processing Service, please see the instructions listed in the TurboTax FAQ below.

Please note that once your e-filed return is in  pending  or  accepted  status, it's too late to remove the Refund Processing Service.

After removing the Refund Processing Service,  you can change your direct deposit information when you go through the interview to file your return (File, File a Return), you will get to the screen that asks How do you want your Federal Refund?, check Direct Deposit (if not already checked), under that you can make changes to your bank information.
