I extended a 2018 form 1040 and recently filed the full return. Due to some miscommunication I didn't file form 8938 but the client DID file the FBAR already. Per the instructions the 8938 needs to be filed with the return and not on it's own so it appears I will need to amend simply to include this form.
Is there an easier way? Nothing on the 1040 changes except to add the form. No schedule B was filed so I guess the amended return will simply be the additional Schedule B with part 3 filled out and the added 8938. Sound right?
