I bought my TurboTax at Staples. Now that I've finished working on it, it wants to charge me again! HELP! I just want to file it.

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.

You appear to be posting from online software instead of the desktop CD/download software that the license code is for.  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.

You are using the TurboTax online edition for your tax return.  You did not purchase the TurboTax online edition.  You purchased the TurboTax desktop CD/Download edition to install on your computer.

You can either return the software to Staples and might get a refund and continue online by paying the TurboTax online account fees.

Or you can use the software you purchased by installing it on your personal computer.  Enter the software license code during installation.  Start, complete and e-file your tax return using the software you purchased.
