CA 8453-OL is a totally stupid form. CA wants you to simply print, sign and KEEP the form in your records. It is to tell YOU that you authorized yourself to e-file.. You do not do anything with the form.
It is really to authorize a paid tax preparer to e-file and has no meaning whatsoever for a self prepared tax return. But the CA FTB, in all it's wisdom, has never seen fit to update it's regulations to recognize self-prepared tax returns - so the form lives on even in self-prepared tax software.
