In the My Info section of the program indicate that you are active military. You must enter a Military W-2 in the Wages & Income section and after completing the W-2 on the screen labeled Let's check for uncommon situations you will need to check the box Active military duty

From USAA?
AFFILIATE DISCOUNT
TurboTax does offer free filing for active military. According to TurboTax, the military discount applies to "Enlisted (E-1 through E-9) active duty and reserve personnel are eligible for the Military Discount. Commissioned officers, warrant officers, veterans, retirees and National Guard do not qualify for free TurboTax Online discount at this time."
To receive in TurboTax you will need to select active military in the about you section. Then enter your military W-2. The discount will be applied at checkout.
I figured it out.
Not only do you need to be logged in via the USAA link, I also had to list my "Occupation" as "Military Officer," and then ensure my Profile listed me as a Armed Forces Member (or whatever it said exactly). Fixing both of the latter two did the trick.
