We can create a Journal Entry to record the payment made, BCS2020.

Before doing so, I recommend reaching out to your accountant for the accuracy of the books.

Here's how to create a Journal Entry:

1. From the + New button, select Journal entry.
2. Select an expense account in the first column.
3. Enter the payment amount on the DEBITS field.
4. Select Opening Balance Equity on the second line.
5. Enter the same amount in the CREDITS section.

Once done, the register will recognize the amount as an expense transaction. That being said, it will not affect your reconciliation.

I've added this article as a guide when reconciling the account: Reconciliation in QuickBooks Online.

There you have it, BCS2020. Let me know if you need help. Keep safe!
