How does military file while their residence is CA, but they are stationed out of CA? Assume no other income. The TT prompts are terrible and unhelpful

State of residence is CA.  I select I lived in another state - because I did, I was stationed there. Then it asked my previous state of residence... NO, I'm in the military, I don't have one.  The entire formatting year after year is jacked in this section!!! HELP
