How to get USAA discount for Turbotax software download (not the online version)

On the USAA website it says:


The available discounts for all USAA members for both Online & Desktop are:

$10 off Deluxe $15 off Premier $20 off Self-Employed (Online) or Home & Business (Desktop)



But when I go to the special USAA Turbotax site, downloads are not listed for the discount, only Turbotax online.  I need the download because I am filing separately with a deceased spouse.
