Can I pay the TurboTax fee with my state refund?
No. The Refund Processing Service can only deduct your TurboTax fees from your federal refund.
This means you won't be able to use Refund Processing as a payment method if you don't have a federal refund, or if your federal refund is not enough to cover your TurboTax fees plus the fees, if any, for Refund Processing.
You can use Refund Processing to pay your TurboTax State fees – you just can't deduct any TurboTax fees from your state refund.
Note: There may or may not be a charge for Refund Processing, depending on your situation and which add-ons you choose.
