Is there a way for me to find out why I have not been paid my state tax refund yet? I've not been contacted by the IRS to my knowledge. Is there a way I could get paid?

I e-filed through CA and it says accepted on 01/27/2025, however, still have not been refunded. I've long received my Federal Tax refund. I'm not the only one to not receive their state tax refunds. What's wrong?
