determining california residency (WFH)

I moved to California from Florida in 2019/09 to start working there with no predetermined end date. I started renting in California after the move.

 

In early March 2020, the company started making people work from home, so I moved back to Florida in early 2020/03, while still working for the same employer. In May, I terminated my lease in California. In July/August, my California driver's license is due, and I get my FL driver's license. (Not sure if this piece of information matters, but the employer initially states that people will not be required to return to office until the end of 2020, and then they postponed the time to late 2021.)

 

My three questions are:

1. Would I be considered a CA resident, or does it make sense to consider myself a CA part-time resident for 2020?

2. How would the answer change if starting from the end of 2020, I started looking for a new job outside of California (Will this show that I'm not outside California for a “temporary or transitory purpose.”)?

3. What if I'm going to accept an offer from an employer outside of California soon? Does that change things in any way?
