Federal Return Accepted 1/17 But Now Shows "Not Processed" - State Still Pending Since 1/21

Filed my taxes early this year, federal got accepted quick on 1/17 but my state return has been stuck on pending since 1/21. Starting to get worried since its been over a week now. I just logged into my IRS account to check my federal status and saw something concerning. It says "Your 2024 Tax Return Is Not Processed" even though I received confirmation that it was accepted! The message from the IRS states: "If you've already filed, processing usually takes 21 days (electronic returns) or six weeks (paper returns)." But I filed electronically and it was supposedly accepted already! It also mentions "If you still need to file, submit your tax return along with any payment due by April 16, 2025 to avoid potential penalties and interest. If you've been affected by a recent disaster, learn about the most recent tax relief provisions to know your options." The strange thing is my federal return was accepted almost immediately on 1/17, but now when I check my account status, it shows as not processed. Has anyone experienced this discrepancy between getting an acceptance notification but then seeing "Not Processed" in their account? I'm especially concerned since my state return has been pending for over a week now too. Is there a difference between "accepted" and "processed" that I'm missing? The whole thing is making me anxious. Anyone else experiencing similar delays or status issues with either their federal or state returns?
