My 2023 tax return still says “accepted” but has never processed. I have not received my state or my federal refund, how do I find out more info how to fix this?

I filed my taxes on turbo tax, everything went fine. When I submitted my return, both state and federal were accepted quickly without any problems. Then nothing… I continue to check on “where is my refund” but the status has yet to change. I have moved, more than once since filing. The IRS may have sent me a letter that I never received, but I do not know for sure. I have attempted to reach somebody at the IRS but I end up getting hung up on by the mean automated system every time. I am scared to file any more taxes, in fact I am late on filing this years, but I am not trying to loose another year into the black hole at the IRS…
