I have enough money from my federal refund to pay for my fees plus the processing fee, but when I click pay with federal refund it goes to pay with CC, why is that?

In order to pay for TurboTax using your refund:

 

• Your federal refund must be enough to cover your TurboTax fees.
• You must have a US address.
• You have to e-file.
• The name on the bank account needs to match the name on the tax return.
• You'll need to direct deposit your refund into a single account.

If you owe taxes to your state, you won't be able to pay for the state taxes from your Federal refund.
