TTS: proper time to file Form 3115

I am now applying for trader tax status  before Apr 18, 2023 at UTAH office, to be effective from 01/01/2023. This is for one account only out of three trading accounts I have.
 
My question is should I fill Form 3115 now with my Account Mark to  Market  total on 01/01/2023,  OR can I postpone that next tax filing deadline, that is Apr 15, 2024. I appreciate if some one with some knowledge about  answer this question.
