Hi there, Janet Bee.

Thanks for bringing your question forward here in the Community. I'd be glad to lend a hand so you're able to complete the reconcile in your QuickBooks Online account.

To make sure I'm on the same page, are you working on the reconciliation for the month of June? If so, I believe the expense amount isn't showing on the reconciliation screen due to the differing dates. I recommend changing the date of the expense to June, and then attempting to complete the reconcile once more.

It's always a good idea to double check with your accountant before completing these types of actions regarding a reconcile. In the meantime, I have an article for you that outlines the process of reconciling an account in QuickBooks Online. 

Please don't hesitate to reach back out with any other questions you may have. I'm only and comment or post away.
