Retirement tax questions

I was finally able to get TurboTax to accept my return, and was able to submit it with my Simple IRA Contribution.  The IRS accepted my return immediately.  This was on 01/31/2024.  I have been checking my refund status each day to see if the IRS had processed my return, and kept getting the standard response"..... it normally takes 21 days....".   ......until TODAY!!!  Now I am getting the following message on IRS2Go:

We apologize, but your return processing has been delayed beyond the normal timeframe.  You can continue to check back here for the most up to date information regarding your refund.  We understand your tax refund is very important and we are working to process your return as quickly as possible.

Has anyone else run into this problem?
