Hi there, joeliz90731.
Thank you for posting here in the QuickBooks Community.
You can follow the steps provided by my other colleague @MaryLandT to pull up the Reconciliation Discrepancy report. This way you will be able to see if there are any changes made since the last reconciliation.
If there are no changes on the report, it's possible that they were duplicate transactions. if that's the case you can remove them.
If the transactions show they were changed, you'll need to make the necessary corrections. For further assistance, I suggest consulting your accountant.
If you have to add entries or you have modified previously reconciled transactions, you can perform a mini-reconciliation.
If you have discrepancies in your reconciliation, you can refer to this article for steps to fix them: Fix Reconciliation Discrepancies.
Please know that you're always welcome to post if you have any other concerns. Wishing you and your business continued success.
