I paid my subcontractor via check prior to QB online payroll -- is there a way to add these payments to the 1099 report because they are currently missing?

Thanks for coming here, @stephanie88.

Let me help you show the check transaction to your 1099 report.

You can run the 1099 Transaction Detail Report. However, to show the subcontractor you paid via check, ensure you recorded and mapped the expense account appropriately. 

Here's how:

1. Go to Reports.
2. In the search field, look for the 1099 Transaction Detail Report.
3. Customize the report and ensure the date range is correct.

You might want to modify your 1099 report by exporting it. Feel free to read this article for more info: Export your reports to Excel from QuickBooks Online.
