Having looked more closely, I'm 99% sure that the amended CA Form 540 is where I sign. It's the logical choice, and is the first form past the 8453-OL form.
My supposition is that the 8453-OL appears because I originally efiled, and if it says not to send it to the FTB, then I should just do as the form says, don't send it.
Thanks,
Kevin
