you say you are a resident of CA, therefore your w-2 should reflect CA wages and withholding
Generally if you work in California, whether you’re a resident or not, you have to pay income taxes on the wages you earn for those services. That’s due to the “source rule”: California taxes all taxable income with a source in California regardless of the taxpayer’s residency. In other words, nonresidents pay California income taxes on taxable California-source income. With respect to employees, the source of income from services compensated by W-2 wages is the location where the services are performed, not the location of the employer.
since you are working in CA., the university should be withholding CA taxes. but it doesn't hurt to check.
