Come back at the end of March when the 1040-X amended return form will be ready. Since it will then take several months to process, BF will have to file his own return by mail.
You said you don't work, but you still filed a return. Was that just to get the stimulus? If you qualify to be your BF's dependent (even if he chooses not to claim you), you do not qualify for your own stimulus payments. Or did you have some other type of income in 2020?
