My refund says processing and see topic 152. What does this mean?

[alearn26]

I filed my taxes about  25 days ago, Turbo says they were accepted. I already received my state refund.  When I got to the IRS website to track my refund it just says your refund is processing to see tax topic 152. I am just wondering if anyone else got this and received their refund?

I filed 2/11 and they got accepted 2/12. I waited the 21 days no updates. I finally called today. It is under review they have no idea why. My letter letting me know won’t be sent out till March 25th and starting on 3/25 they had 45 days to review it. I have to call back on May 5th if I still haven’t received my refund.
