When entering your personal information in the My Info section of the program and you have indicated that served in the Armed Forces, the following screen asks for your military status as of 12/31/2018.  You should have selected Active Duty Military since your Guard unit was activated and you deployed for combat duty in November 2018.  Then you are asked about your military status for the year which you should have indicated that you were in the military all year (that covers your Guard status and activation status).  A few screens later you are asked about being in a Combat Zone or Hazardous Duty area in 2018.  Since your CZ is not listed just select Other Combat Zone.
