Where do I send my CA 1099 misc state forms?

If you are an employer, the Franchise Tax Board.

If you are an employee, you send the form NOWHERE.

If as an employee you have received 1099-Misc, then this is self employed income and is reported on schedule C (Form 1040). This income is subject to SE tax at 15.3%.

How you will treat the 1099-Misc income, read: Your U.S. Tax Return: W2 or 1099: Employee or Independent Contractor.
