Yes, "quite stupidly" Why do corps get 10 days to refile and 1040, and 1041 only 5?
I actually had one this year where one of the dependents names didn't match, even though I had a copy of the SS card. There were four names on the card, so I tried various combinations, of first and last names, but nothing matched. The client ended up mailing it in.
BTW, thanks for the link. That is a handy chart.
