Barbara's answer was right. That is how to download the CD program like if your CD drive is not working or you can't install the CD. It is not to use the Online version. You should also have a card in the CD box that says how to download the program instead.

Do not click on the bottom link to Switch to TurboTax Online. That takes you to the Online web versions and not your Desktop download.
