They didn't start processing until 2/12/2021, only 3 days ago. I filed my California return on 1/14/2021, I got a notification yesterday, 2/14/2021, that it had been accepted. Took an entire month for mine to be accepted, but that's because California didn't start processing until AFTER the IRS started on 2/12/2021. Both my Federal and California have now been accepted.
