If your TurboTax account fees are $89, there is a Refund Processing Fee of $39.99 to pay the account fees with the federal tax refund.

TurboTax will not allow the use of the Refund Processing Service if the amount to be paid from the refund plus the Refund Processing Fee is within a certain percentage of the federal tax refund.  You will have to pay the TurboTax account fees with a credit card, which is going to save you the $39.99 Refund Processing Fee service charge.
