The following will have information about why someone can not use their Federal refund to pay for their TurboTax fees.

Why can't I deduct my TurboTax fees from my refund?

There are several situations where you won't be able to use the Pay With My Refund service, including:

• You're filing a paper return
• You don't have a federal refund
• Your federal refund isn't enough to cover the fees
• You're filing with a foreign address
• Form 8888 is in your return
• You already used the service when you initially e-filed your federal return
• You already filed your federal return and are now only filing your state return
