State tax filing

It depends how you reported your California income.  When you prepare your California return, You will allocate the amount of California income earned in California. I have included a screenshot of that screen where you report the California allocation. 

You do have a certain amount of tax liability to pay inn California even though you are strictly a non-resident. if you did not have enough withholding tax taken from your California W2, it is possible you may owe California taxes. In my scenario I prepared for this answer, on $60K worth of California income, the tax liability was $1351 (for a single filer).  If there were no withholding done, this person would have owed $1350.  Your may be more or less depending on your filing status.  Here is the screen in the California section of your tax return where you allocate your income. Be sure to check your entries to make sure no other income is allocated to California.
