the 1099 NEC don't have EIN number, only SSN, it kept asking for it. And the result won't let me e-filed. What should I put in Payer's EIN when there is none

Since you said the 1099-NEC has a Social Security number instead of an EIN, you can change the format of that field to accept an SSN instead.  

In that same general area on the input screen there should be a question asking how the payer's Federal ID number is formatted.  Choose the option that shows xxx-xx-xxxx to enter the SSN.
