Can I leave the Where was I stationed question blank if I lived in the same state all year? It says add each state I lived in and reason for move, but I didn't move

When asked about which state(s) you were stationed in, select the state you actually lived in during the tax year.  Since you permanently resided in the state, use "Permanent Change of Station."  

If you were only in a state for a temporary duty period then you would select the "Temporary Duty" reason.
