I can't be the only one who received letters with the incorrect amount for the advanced child tax credit, can I? I'm thinking that some of our checks went missing.  

Of course, I will try to figure my situation out (especially since I should have opted out) but I imagine I will have at least one client who is in a similar situation.  Other than fruitless attempts at making it through the phone lines, has anyone heard of ways to deal with it?
