Thanks: I've asked them to and they said they'd look into it and see. Is it very difficult to change a 1042-S once it has been issued?
For unrelated reasons, I have to file an amended return for 2016, and one of those forms didn't have a SSN on it. When I file the amended return, I guess I just send in the old 2016 forms (one with the SSN and one without)? They don't have to give me any money back, I'm the one paying them in this case, so that shouldn't be a problem, right?
