eConnect was not updated for the new 1099 NEC which we have called out in our blog about the 2020 year end for payable below.
 
Microsoft Dynamics GP Year-End Update 2020: Payables Management form changes including the NEW 1099-NEC!! - Microsoft Dynamics GP Community

Question 7: When I try to integrate payables transactions with the new 1099-NEC tax type, it doesn’t work.
Answer 7: The new 1099-NEC tax type/boxes were not added to Integration Manager or eConnect and are not supported with those integration tools. 
 
To get around this you would have to use post or pre process in eConnect for the new NEC changes.  Here is an example from the GPUG communities on how some are going about this.
