If you have the CD/download you can prepare and e-file up to five federal returns. If you are using online TurboTax, each return needs its own account and user ID, and you pay for each federal and state return.
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.
If you are using the TurboTax online web-based editions those can only be used for one tax return per account and User ID.
If you are using the TurboTax desktop CD/Download editions installed on your personal computer you can complete and file as many tax returns as needed.
Click on the File menu at the top left of the desktop program screen. Click on New Tax Return
