I am having the same problem with Quick Employer Forms. A 1099-NEC that was accepted last year is now being rejected for 2023.
I found and called the Turbotax contact number (thanks for the tip on how to find) and spoke with an agent with lots of experience. However, they were not able to help. At all.
Now I am changing our "Business Name" to match my husband's name since we use his social security number and refiling. Hoping it will go through this time!
