BTW: You might ask what is the difference between a PDF attachment and a e-file form since they can both be e-filed?
The IRS programs their processing computer to automatically process e-filed forms, but attachments must be flagged and set aside for a human to look at and manually enter - an attachment can be anything. Anything at the IRS that involves humans delays the refund process considerably.
