Ohh, ok, I think the 3537 is for paying the actual "tax" (when you owe more than just the 800 annual fee, I dont have any of these).  If you only want to pay the annual 800 fee, just send in the 3522 with the 800 payment for 2023.  CA doesnt want an extension if you dont owe taxes...the 800 isnt a "tax" its a fee.
