Is it possible to recover (undo, undelete) a deleted journal entry?

You're unable to undo a deleted journal entry. However, you can utilize the Audit log to view the information in the journal entry and recreate it. I'll guide you through the steps below.
 

1. Go to the Gear icon and select Audit Log.
2. From the Filter dropdown, select the appropriate user, date, and event(s).
3. Locate the deleted transaction.
4. Under the History column, select View.
5. Please take note of the details so you can re-enter the journal entry with its original transaction date.
