Hello there, danerk. Let me share some important details on recovering your deleted transaction from the opening balance equity account using the audit log. 

QuickBooks Online has an audit log feature that lets you keep track of all your activities and modifications within the software. This feature provides a comprehensive record of all the movements you've made, allowing you to monitor and review every change you've done.

If you've accidentally deleted some transactions and need to recover them, I suggest manually adding them back using the audit log. This feature will help you add back the deleted transactions since you can view some details of the transactions there.
