Okay, I got some updated information from development about this issue this morning. It appears as though the forms are not final and that e-filing has not yet been approved, which is why we're seeing the transmission failure. It sounds like we are targetting a release of 2/21 for the NC forms with agency e-file approval. Our development team is working with the agency to ensure this is their final version and will be ready for e-file on this date.
