Yes, you can go through the File section to pay TurboTax fees, just don't go to the end to file your return.
To pay for TurboTax: before you file:
- Open or continue your return
- Select File in the menu and then select Start next to Step 1 Review your order
- Select View payment options
- Select Pay now(or Pay with Federal Refund, if that option is available) to make your payment
Because paying for your TurboTax Online fees is separate from e-filing your return, you can pay at any time prior to filing your return.
