I have the Turbo Tax CD but my computer doesn't have a drive. I went through the online tool and got to the screen where I pay to file. Is there any way I can enter a code from the CD to offset the fee? I saw you can download the CD by calling and providing info, but then I would have to go through the whole thing again. Is there a way I can get an online code if I call in with the CD info? I saw a spot to enter a service code...
