Program will not accept a may reconciliation/

Good day, d-bouchard. I'd like to ensure we're on the same page so that I can provide you with the right information or instructions to address your query.
 
May I know what specific assistance you need with reconciling your bank transactions? Have you encountered any error messages while attempting to reconcile within the QuickBooks program?

Also, would you mind including some screenshots so I can get a better view of it and share the best solution with you?
 
I'd appreciate any further details you can provide so I can help you. I'll keep an eye open for your response.
