Wheres my refund

I filed my taxes with turbo tax on March 14th 2022, I received an email from the irs the same day saying that my refund was accepted.  I felt great because it seemed like they accepted it really fast.  So now it's been almost a month since I filed and been accepted,  but its still processing.  😔,  I keep checking the irs/refund app and website, but all it says is that there sorry but my refund is taking longer than expected.  And I was wondering why this has happened and should I be worried ? I got the max benefits with my taxes , so I feel like im covered by turbo tax God forbid something happens, but I need my tax money, and for some reason I wasn't able to sign in to credit karma to get a advance on my refund. So there is nothing I can do is wait . But I really need the money for a home im trying to get my family in

 Is there anything you can help me with ?
