Hello RhoiceW, I appreciate your prompt response, thanks. 

Perhaps something was misunderstood, as you're referring to "threshold not set to zero that's why vendors with $0.00 are appearing on the report"

That is not the issue I'm describing, I'm referring to Vendors still being listed who do not meet the $600 threshold, ie their Total is less than $600 (but greater than $0).   Please review what I wrote:

"When producing a 1099-NEC Detail Report, it still includes Vendors who do not meet the $600 threshold, and I don't see any way provided by QuickBooks to exclude these Vendors. Filtering for Amounts less than $600 is not appropriate, as that removes transactions that should not be excluded. We need to be able to filter for "Totals" less than $600.

(I had already previously checked the threshold setting that you describe, and it is at 600 as required.)

Perhaps you can take another look at this issue, how to filter for Totals less than $600, and see what can be done about it please.

Many thanks, Peter
