I hope I understand your question. Are you asking about a payment method for your product fees?
Are you asking if you can pay your product fees by using a pre-existing debit card you already own instead of a credit card? If so, then yes, TurboTax will accept a debit card for payment as long as it has a Visa, Mastercard, Discover, or American Express logo, and has a USA bank with USA billing address.
A TurboTax screen may only mention pay with "credit card," but it should also take a debit card.
If that's not what you are talking about, then you need to explain it in more detail so we can understand what you are wanting to do.
