I'd like to help you get the transactions sorted out, Rory.

Looking at the situation, it seems that the payments showing up in the Bank Account History are not linked to the overdue invoices. What we can do to correct this is to remove the payments you've recorded. Then, undo the transactions that were added from the banking page. This way, we can match the payments to the overdue invoices and reconcile your account.

To delete the recorded payments, here's how:

1. Go to Sales on the left menu and select All Sales.
2. Select the Filter drop-down menu and Money Received from the Type drop-down.
3. Choose the Date and click Apply.
4. Open each payment and click More located at the bottom.
5. Select Delete and choose Yes to confirm.

Please see sample screenshots below for reference:

Then, let's go to the banking page and undo the transactions.

Here's how:

1. Go to Banking and select the Banking tab.
2. Select the bank account where the transactions are added.
3. Click the Reviewed tab, and click the Undo link of the transactions that matches to overdue invoices under the Action column.

Once done, we can now match the downloaded transactions to the overdue invoices by following these steps:

1. From the Banking page, click the For Review tab.
2. Click the Match link under the Action column. If you can't see a Match link, then select the transaction and choose Find match.
3. Select the invoice that matches the downloaded transaction.
4. Click Save.

That should fix the transactions in QuickBooks and in the banking side. Then, we can start reconciling your bank account.

Please don't hesitate to reach out if you have any additional questions. Thanks.
