This is when you agree to use our Refund Processing Service which is an option for paying your TurboTax fee by deducting it from your federal tax refund. It's a convenient way to pay for TurboTax if you don't have (or don't want to use) your credit or debit card.
You do not need Refund Processing Service to e-file and process your refund and refund processing won't slow down nor speed up your refund.
There is a charge for this service, depending on your situation and which add-ons you choose. We'll display the fees, if any, when you get ready to file.
If you have other questions about this, ask in the comment section below.
