Thanks for sharing your concern with us, MKT22191.
Let me share my input regarding your concern on treating the payment on hold in QuickBooks Online (QBO).
You're doing the right thing. Since you've already excluded the payment on hold from your banking, you don't need to record it in QBO.
Get back to me if you have other questions. I'm always happy to help you further. Keep safe and have a great rest of the day!
