@User49462 - again, take the time to read the link and noted sections:
Look at Section G and H on Page 5
https://www.ftb.ca.gov/forms/2020/2020-1031-publication.pdf
CA does say you are considered a 'full year' resident, if you spent more than 9 months in the state; you did not. (which tells me you probably didn't read the material 😊)
How can you be a part time resident of CA, unless you are stating you kept moving your permanent residence back and forth between Florida and CA during the year. Did you keep changing your drivers licenses? where you were eligible to vote, where you registered your cars? I suspect not.
please read the material!!!!
