Employer refuses to change work location/update w2 despite me breaking residency from CA

I moved from California to Florida in 2020. I went to Florida in March and then went back to CA in June to finish moving out of my apartment.

 

However, when I reached out to my employer to change the work location (for withholdings), they declined, stating that they will not change people's work locations during COVID.

 

As a result, my w2 still states that my work location is CA, despite me not having been there since June. (I have no accounts or assets of any kind in CA).

 

1) Do I have to pay CA taxes because my w2 says CA and won't correct it? Or can I still file as a partial resident to CA?

 

2) Do I need a tax attorney now to deal with an audit if I file as a partial resident?
