I have completed my tax return but Intuit turbotax is asking for payment. I have purchased a turbotax already, but cannot figure out where to enter the license code

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.

Are you using TurboTax Desktop or TurboTax Online?

There is no license code required when using the TurboTax online editions. You enter the license code as part of the process to set up TurboTax desktop software you install on your personal computer.

Here is how to switch to Desktop.

See this help article if you have a discount code to enter.
