Hello office-alignst-g,
It's nice to see you in Community. Welcome! Reconciling your accounts in QuickBooks Online is a great way to keep your books balanced and aligned. with your monthly bank statements. When a transaction has been deleted, it can definitely impact the reconciliation process. I would be glad to help!
When a transaction is deleted in QuickBooks, it cannot be undone. You can review the item by going to your Settings ⚙, then select the Audit log. However, you will need to recreate the deposit, making sure the Date and Account information is accurate. This will ensure that QuickBooks can match it with your books. Once you've completed these steps, you're ready to reconcile your account.
