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.
See this TurboTax support FAQ for the license code - https://ttlc.intuit.com/turbotax-support/en-us/help-article/product-system-requirements/find-license...
