Hello there, @kl9.
I'm here to help you match your bank reconciliation to your trial balance in QuickBooks Online.
To isolate the cause of the bank reconciliation isn't being a match with the trial balance, we'll have to make sure the dates for each report are the same.
Otherwise, you'll need to make sure that all transactions in the reconciled period have already Reconcile status. The unreconciled transaction will cause a difference in your bank reconciliation. check the dates on the individual checks and deposits.
I've attached this article to learn more about running and customizing reports, you can check this article: How to customize reports.
You can always add a comment below if you have any other questions in QuickBooks Online. I'll be right here to help you!
