THANK YOU fellow users!!! Based on the comments/inquiries regarding Form 8453-FE potentially being the problem, I removed the Form 8453-FE and reattached (following the instructions for changing the form even though I reattached the same form with no changes). I'm happy to report that the Trust return has been successfully transmitted and is awaiting IRS acceptance. "No news is good news"....if you don't see another post from me it was also accepted. THANKS AGAIN to my fellow users who looked for new solutions and didn't just keep repeating the same steps that were NOT working.
