1099 NEC income for the Federal and CA state return

Hi.

 

I'm not a contractor, but I received a 1099 NEC form from my employer. 

For the federal return, am I eligible to use a qualified business income (OBI)?

 

CA return- Am I required to be treated as an employee for California purposes even though I received a 1099-NEC form for federal purposes? Do I need to adjust the amount of my income from the 1099 form and deductible part of my self-employed tax?

 

Thank you.
