Paid for premier program with Costco. asking for additional fee ?

Did you install the program and enter the 16 digit License Code to Activate it?  Looks like you ended up in the Online version by mistake.

Sorry you can't apply the Desktop CD/Download program purchase to the Online version.  They are separate prices and work different.  You have to pay for online and try to get a refund for the Desktop program.  Or switch to your program.

To Continue in your Desktop program......

You need to install the program on your computer and move your online return to the Desktop program. You can move your Online file to the Desktop program and continue without paying for Online or needing to reenter your info.

To continue in the desktop version see this…….

After you get the program installed the first thing to do before you open your tax return .tax file is to update the program and install any state programs you had. Then open your file. So you first might need to start a fake return to be able to download the state program (go to FILE - NEW).
