I am being charged $39.00 to use Turbo Tax but then when trying to checkout it says an additional $40.00. Am i being charged a total of $79.00 to use Turbo Tax?

How can I see my TurboTax  fees?

If your TurboTax fees are higher than expected, you can reduce them by removing add-ons     (BEFORE you e-file) :

• Remove Premium Services
• Remove MAX Defend & Restore
• Remove a state
• Remove PLUS Help & Support

• Remove Pay With Your Refund

You do not have to pay $40 to have your fees deducted from your federal refund.  Pay your TurboTax fees upfront  BEFORE  you e-file --using a credit or debit card.
