Refund delayed due to IRS requests

My 1040 2022 efile was accepted Mar 9. Instead of the much needed refund, I get a letter from IRS requesting I provide W2 and retirement 1099 to prove the taxes I paid.  All taxes were withheld at Statutory rate from my Deferred Comp W2 and RMD's.   The IRS withheld these taxes and should have copies of W2 plus the 2 retirement 1099.  Why would they ask for these again ? 

 

It felt like a scam but the letter and addresses seem valid.
