Sometimes, as QuickBooks matches downloaded transactions to ones in the register, it makes a match that you don't agree with. When this happens, you can manually undo the match.
To do this task
Open the Add Transactions to QuickBooks window.
Click a transaction in the left pane with a Matched status that you want to unmatch.
Click the Not a Match button.
QuickBooks changes the status of the transaction to Unmatched. You can now manually match the transaction to a different one in the register.
QuickBooks will not try to match the downloaded transaction again. You can delete the downloaded transaction and then reconcile the transaction in your register manually.
