You're a full-year Hawaii resident if you were a resident for the entire year. A resident is someone who considers Hawaii their permanent home or who lives in Hawaii for anything other than a temporary or transitory purpose.
If you spent more than 200 days of 2020 in Hawaii, you are considered a resident. This means you should choose full-year or part-year resident for your residency status unless you can show that you maintained a permanent home outside the state and were in the state for a temporary or transitory purpose.
Note that students and military members have different requirements.
