Assuming you are an enlisted member.............and are using the "Online" software.

There are two spots you have to make sure you have entered the correct entries in order to get the "discount":
1) Edit your name in the My Info section, and make sure you indicated you were active duty during 2021, and your rank.
2) Edit your Military W-2. Step thru the main W-2 entry pages with all the proper $$ boxes filled in, and there will be a follow-up page with a whole bunch of checkboxes on it. You need to check a box that indicates that the W-2 is for your Active Duty military pay.
Once both of those are done, your filing should be free (except for any taxes you might owe).
