I called PPS yesterday to inquire on 4 clients with same situation.   2 efiled/accepted February; 2 efiled/accepted March       3 of the 4 had a child in 2020 - so return has RRC credit.   The agent said all these returns are requiring a manual review. Says the IRS department handling these is behind so expect minimum of 10weeks before the return can possibly be released.   Could be longer if it is determined a letter needs to be sent to taxpayer.  

Made the calls as a courtesy to my clients - 2 of the 4 called yesterday inquiring if I had any news.  Clients are Amish so no access to a computer to check Where's My Refund.
