@Guavalord54 --
If you moved to NV in September with the intent to stay permanently, abandoning your CA domicile, then you would have become a resident of NV - and ceased being a resident of CA - in September.
If that's the case, for 2020 you would file a part-year resident return for CA. All your income prior to your September move would be taxable by CA.
Once you became an NV resident, only your CA-source income - if any - would be taxable by CA.
NV, of course, has no income tax.
