Let's make sure that the date when reconciling is correct, Iclark.

Incorrect Statement date is one of the reasons why the transactions won't reflect when reconciling it. Let's also open the transactions to see if the date when creating them is correct.

Also, another reason is that the transaction has been reconciled already. We can go to your Chart of Accounts to see the status of it. You'll see a check-mark if it's reconciled.

You can read this article about reconcile workflow in QuickBooks Desktop. This will show you what are things you need to do to keep your accounts in balance.

Get back to me anytime of you have any more questions. Take care!
