A Form 8621 (PFIC Form) reportable entity can't provide its address information for some unknown reason. What address information input will get a Form 8621 qualified for e-filing? I've tried "address available upon request" in several fields but I can't put that in the Country input, which (I believe) is why e-filing continues to fail. Trying to "Disable E-file Error" does not get it through either. Thanks.
