I have PDF attachments for an E filed S Corp income tax return that are attached as an "other type" documents. The diagnostic  report for the return gives me a message "If the category is Other", electronic filing in not allowed (document category). No error is cited during the review function. Does this mean that the attachment will not be submitted on an E file basis? I checked a C Corp returns diagnostic for the same documents and the message is not included on that diagnostic. I would appreciate any insight any of you have regarding this issue.
