Not sure about the OK part.
But the "Active Duty" selection after the DFAS W-2 only shows up if the person involved indicated they were Active Duty in the My Info screen...and Yes, even of it was one day during 2020, you need to mark that "I am a member or former member........" , and when you edit the information for that person, as you go thru that in the My Info section, on one of the next pages, you can then select whether the person was active duty all year, or was only part of the year.
