Tax help for military filers

1) In my case filer was active military for only first part of the year... then retired.  So for this 2020 return the person is no longer "active duty" 2)  Nowhere on the W-2 or screen following is there a marking for "active duty" and 3)  In the TT Oklahoma Return there is no option to indicate "military pay exclusion."  There are options for military pay for deceased personnel and for widows of deceased persons, but no option for military pay that is 100% excluded from Oklahoma Tax. 

 

Please advise
