Who can I contact about my refund being accepted but I have not received it for three months

I filed my taxes on 2/18 and I received my federal within a few weeks. My state return, however, is still sitting at accepted. I have tried contacting the IRS and the phone hangs up every time. I have not received any letters in the mail. No contact at all. I have also tried the online system and it’s the same information as TurboTax- federal was received and state is still just accepted.
