I appreciate you for making it this far, Clio. Let's collaborate to resolve your remaining balance once and for all.

Based on your screenshot, it looks like a duplicate entry was recorded. It also appears you've already closed the credit note or supplier credit after creating a bank deposit and using the Pay Bills feature following the recommended steps provided by my colleague.

Since you already had an expense transaction before this, following the steps to create another is the reason behind the remaining balance. That said, we can void or delete the entry that wasn't linked to the bank deposit to clear things up. 

Here's how you can do it:

1. Head to the Expenses menu, then Suppliers.
2. In the All Transaction dropdown, select Expense. 
3. Click the expense transaction. 
4. Hit More, then Void or Delete.

Moreover, I'm adding these additional resources to help reconcile your account seamlessly after categorising and matching your transactions:

• Learn the reconciliation workflow in QuickBooks
• Reconcile an account
• Fix issues the first time you reconcile an account

Maintaining accurate records is crucial for your business's success. If you have further questions or need more assistance managing and recording your bank transactions, I'm here to help.
