A transaction that's waiting to be matched means it's not yet added to the bank register, Drjcwood. Allow me to share details on how you can handle this entry.
Can you also confirm whether the reconciled transaction has been matched before? If it has, the downloaded transaction is considered a duplicate.
Furthermore, if the reconciled transaction was manually cleared before the system added it to the For review tab, matching is no longer possible. This is because this process can only be applied to transactions that are uncleared, unreconciled, and not yet paired with another entry.
In both situations, you can use the Exclude function to remove it from the For Review tab. Here’s how:
- Go back to the For Review tab.
- Select the checkbox of the transactions to exclude.
- Click Exclude.

Once done, the transaction will be transferred to the Excluded tab.

Here's an article about this for more details: Exclude a bank transaction you downloaded into QuickBooks Online.
