Question about filing online with the CD

[mppsu2003]

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...

Thanks...I did see that but that looks like I would have to install the software and go through the whole thing again from the beginning.  Since I already filled out online, I was just curious if there a was another way.
