I would like to cancel the pay by refund for the upgrades chosen and start over. Is this possible?

Instructions to remove the Refund Processing Service before you e-file:

1. Sign in to your online return, if you're not already signed in.
2. Click File in the upper right corner and proceed to the Just one more step screen.
3. On this screen, click the first Revisit link (next to You've chosen to deduct your TurboTax fees from your federal refund).
4. Click View Payment Options on the next screen, and then select Pay with credit card on the screen after that.
5. Complete payment by entering your credit or debit card information.
6. Continue to the Just one more step screen to make sure the Refund Processing Service has been removed. Step 1 should now show that you paid with your credit or debit card.
