Moved from one state to another at the end of the year

I moved from MA to AZ at early December last year for work and was living in a hotel until early this year. Initially the tax was withheld for both states, but was adjusted after telling the HR (which happened earlier this year). I have received the w-2c with box 16 corrected to 0 for MA while the part for AZ remain unchanged.

1. What would be the correct way to file? Part year for both? One full year and one non-residence?
   1. Uncertain about it as I did not have a permanent address in AZ last year nor did I apply for any resident documents such as driver license. So not sure if I count as resident of AZ.
   2. I also was receiving public health care provided by MA as I was unemployed before moving to AZ. In order to be receiving the health care, I'd have to be residence of MA, so I can't file non-residence for MA.
2. What should I enter for the state wages?
   
   1. 0 for MA and full amount for AZ (corrected box 16)
   2. full amount for both states (box 16 before corrected, wages for both states appears the same value)
   3. allocate income between the two states according to your dates of residency (11/12 for MA and 1/12 for AZ)
