Your post indicates you are using the TurboTax Deluxe online edition -

Deluxe online edition for a federal tax return - $40

State tax return when using the Deluxe edition or higher - $40

Option to pay the TurbTax account fees with the federal tax refund - service charge $40

If you do not file a state tax return, do not request to have the TurboTax account fees paid from the federal tax refund, request the optional Max benefits package, or Upgrade to one of the higher editions then there would not be any further charges.

Additionally, there are no e-file fees when using the online editions, federal or state.  You only pay for the use of the TurboTax software to assist in completing the tax return.

You are posting from online Deluxe--which costs $60.  If you have to prepare a state return it is another $50, or if you choose to add extra features like MAX you have to pay additional fees.  If you already paid $60 for Deluxe you need to go to exactly the same account with the same user ID to finish preparing the return.

Many people have multiple TT accounts and forget how to access them.  Log out of the account you are in now.
