Completion of active duty in 2019

I was Military active duty in 2019 until end of November and stationed in NC with PA as my SLR.  In December I started a job in NC and updated my drivers license to NC as new residence. When I file Fed taxes, do I update my personnel info to reflect my current NC address even though I was in NC just for one month?   2nd question, what about filing my state taxes? Do I have to file one in PA for the time in the service and then another in NC for the state withholdings from my current job for that time?
