What do you mean you are looking for where to put the license code "after doing the filing?" You needed to enter your license code in order to download the desktop software BEFORE you prepared a tax return. Did you use online TurboTax by mistake?
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.
If you bought a License Code you need to download and install the Desktop program. You seem to be in the Online version. You can move and continue your Online return in the Desktop program.
