1099-NEC - several Copy A's were not generated

I have 4 contractors to whom I issue 1099-NECs. When I completed the 1099-NECs, TurboTax only generated Copy A (file with the IRS) for 2 of those: the one to whom we paid the most and the one to whom we paid the least. I've been unable to get the other 2 to generate. Since these must be filed with the IRS by January 31, I'm desperate to know what to do. Please help!
