Do you have a DFAS w-2 entered and do you have your enlisted rank entered? Enlisted and Active Duty: As long as you have a w-2 from DFAS entered in TurboTax and your rank is entered as E-1 - E-9 in the My Info section (see below), TurboTax will automatically apply the discount. Military Promo - Thank you for your service!
You may need to delete the w-2 and re-enter it if the discount is not applying. See Military Discount Help
