@chilicheng , please tell more about your situation such as
(a) When did you enter the USA ?
(b) with which visa --(F or what )
(c) Which country are you from ?
(d) Was your work/earnings under EAD or what ?
(e) Was your filed return accepted for processing, or already processed and refund issued or what stage is the return in ?
(f) Did you receive a W-2 or 1042-S for your earnings ? Or was it something else ?
Once the situation is clear then we can go into the process of filing an amended return -- if needed.
I will circle back once I hear from you
