The TurboTax fees are the same whether you efile your return or print it and mail it. In other words, there is no additional fee for efiling your federal return so therefore there is no refund for filing paper instead of efiling.
If you used the Online web version the fees are to prepare the returns whether you efile or print and mail. Efiling is free and included.
If you used the Desktop CD/Download program you get 5 free Federal Efiles. It is 19.99 or 24.99 to efile state or you can print and mail state for free.
