Hello there, @Ej.
Let me share some information on how QuickBooks handles your Venmo bill payments.
The ability to directly pay your vendor bills using Venmo within QuickBooks is currently not available. You'd have to make the actual payment using the Venmo app. Then, you can manually track the payments you've made in QuickBooks and match it with your downloaded bank transactions.
Just select Check, then Assign check number even when you’re not paying it with an actual check. Enter the type of payment in the check number field or leave it blank.
You can read through this article for more detailed steps: Pay bills in QuickBooks Desktop.
