Get your taxes done using TurboTax

I followed the link and select download TurboTax for Mac and selected the correct edition.  It just submitted a support ticket.  I'm surprised that I can't just get the download link—I have the license key and PIN from the packaging handy already.  Is this the right method to get to the download?  It sounds roundabout.  The front of the box proudly says "Two way to install—CD or Download" and instructions on the back—but there are no instructions for actually downloading the software.  Please help!
