Did you or her download and install the Desktop program? Do you each have a License Code?
There is a way to have 2 licenses. You don't need to install the second version just enter the License Code. Under Help - Switch Product - Activate new product. Don't know what that will do or what benefit you will get. Don't think it will allow you to efile more than 5.
Or are you trying to enter it into the Online version? The License Code is for the Desktop program. You can't apply it to Online. How to get started with the Desktop program, install and activate it
