That isn't really a workable option in this case as I have 145 partners in this return.  I know I will have to print and send in the K-3 schedules, which will be too large to attach via pdf, but was hoping to resolve this error so the forms are correct when printed and so the return can be e-filed.  If I enter an arbitrary country in the drop-down list, all errors resolve, but RIC is not in the country list even though this should be a valid entry and this would mean correcting all 145 K-3 forms by hand before mailing.  I don't mind a delay if I know this will be fixed in the next few months as the return is already on extension.
