There is not a download code if you purchased the TurboTax software from the TurboTax website - https://turbotax.intuit.com/personal-taxes/cd-download/

You only need to sign onto the TurboTax download website with the User ID used to purchase the software so you can download the installation file - https://shopping.turbotax.intuit.com/unified/downloads?route=myaccounts&cgcview=downloads

When you are installing the software on your computer you will be asked for the license code to complete the installation.
