Regarding the diagnostic messaging, specifically the portion that indicates "If you are filing electronically, make sure to exclude these forms before filing any information report."

The program does not provide a way to suppress these forms, other than removing the input that is triggering them. Once the details are removed, the information report can be electronically filed and will not be rejected due to the 05-177 or 05-166 no longer present in the filing.

Note: If either the Form 05-166 or 05-177 is required to be included in your filing, the return will need to be paper filed.
