Final answer:
Apply the Pending Review filter to see all the transactions QuickBooks Online thinks it has found a good match for.
Step-by-step explanation:
To filter for the Review tab to see all the transactions QuickBooks Online thinks it has found a good match for, you need to apply the Pending Review filter. This filter will show you all the transactions that are pending review by QuickBooks Online. Transactions that have been matched or unmatched will not be displayed with this filter. Therefore, the transactions you will see are the ones that QuickBooks Online deems as potentially good matches.
