There is no e-file fee when you are using TurboTax Online. But if you have not yet paid for the TurboTax Deluxe preparation software that you are posting from and that state download, you will see a charge for those. And if you added any add-ons, you will see a charge for that.
You can click on Tax Tools over to the left of the screen and then click Tools. When the box pops up, click My Fees and that will show you what you will be paying for if you have not already paid the TurboTax fees.
