What is it charging you for? When you use desktop software which you have purchased in advance of using the software, the only additional fees are for e-filing a state return for $25. You can avoid the state e-file fee if you print and mail the state instead.
Or....have you made a mistake and did you use online TurboTax instead of using the desktop software?
We see people get confused and they keep logging in to online software which will require them to pay at the end. You need to use the desktop software. One way to tell if you are using the right software---your tool bar. Online software has the toolbar in a black vertical column on the left side of the screen. Desktop software has the tools up on the top of your TT screen.
If you are using online, you are using the wrong program. You need to switch to the desktop software to get what you paid for. You have to download it, update it and open it up from your own hard drive to use it.
