Refund HELP

I sent in my son's very simple tax return on 3/4/22.  There has not been a refund sent.  When i go online with him at IRS website "Refund" it continues to say there is no information or I must have done something incorrectly -- Everything is correct - SS#, amount of refund and date.

 

It was a paper return mailed in.

I cannot find anyway to get anyone to talk to or contact.  I am concerned maybe a check was stolen or??? 

It has been over 12 weeks. 

Any help is appreciated
