TurboTax provides a service—preparation of federal and state tax returns. TurboTax wants to be paid for that service. The amount of service TurboTax provides is the same whether you are getting a refund or whether you owe taxes.
TurboTax offers free preparation for simple returns, but the final price is determined by the forms that you need included in your tax return, and not by the amount of tax you owe or refund you are expecting.
