On Schedule C you will check box 522(b)(3), this is because California has opted out of the 522(d) Bankruptcy Code exemptions. However, you will still need to provide the applicable code section for the exemption you are seeking.
California state law gives you the option to choose between (1) a set of state law exemptions similar (but not identical) to the Bankruptcy Code exemptions; and (2) California's regular (non-bankruptcy) exemptions. You need to check out which set of exemptions better serves your purposes.
I wish you the best of luck in finding a resolution to this matter.
