I don't have the complete answer u need but the number that starts with 999 is not a temp ssn, it's an ID no. For int'l students. (In Texas) an international student can't file a 1098t legally, unless you are married to us citizen. Most of my friends did so anyways, without getting in any trouble , as far as I know. But since u don't have a ssn I don't know how that goes.
