I'm a military spouse living in HI but home state is CT. My W2 has box 15 filled in for HI. How do I enter to make sure I am not having to pay more than I should?

I am a military spouse who is trying to file jointly with my husband. We are currently in HI due to him being stationed here but our home of residence is CT. When we enter in my W2, the box 15 says HI but no taxes have been taken out during the year. If I enter it in, it is stating I owe for CT and HI. I know I should not be having to pay state taxes due to me being a military spouse. How do I properly enter the information to ensure I am not paying extra with my taxes? Am i to leave box 15 blank? Or what do I do so that my exemption is being properly added in?
