I ended up speaking with Turbotax support and they suggested changing a few zero entries by blanking them out. I shared my screen with the support agent and she directed me to the different zero entries she thought might be causing the rejection with no reason provided. She also indicated that if it was not successful, I would need to mail in the amended return.
I resubmitted my E-file of my amended return and it was eventually again rejected. I ended up mailing in my return to the IRS.
JulieS, thank you for your reply.
