You must have misunderstood something. The federal taxes owed can never be paid from the state tax refund. Only the TurboTax account fees can be paid from the federal tax refund using a third party processor and there is a $40 service charge for that option.
The federal taxes owed can be paid using a check, direct debit from a bank account or by credit card.
Go back and review Step1 for the TurboTax account fees and Step 2 in the File section to see exactly how you chose to pay the federal taxes owed.
