I too filed my taxes back on February 9th and my Federal return was accepted on February 11th, however, my California State tax return is still showing in the "Pending" status.  I am thinking they are perhaps just backlogged and taking longer this year to get to returns.  Generally, my returns are accepted right away.  This is the longest it has ever taken to go through.  I am sure there is nothing to worry about. @noperfectangels   Let me know if/when yours goes through and I'll do the same.

The same thing happened to mine.  I efiled on 2/15/21 at noon.   The fed confiremed within an hour.  Still waiting on state confirmation.  In the past they always came back the same time.  Seems odd.
