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

I've attached these articles for future reference in case you need to reconcile those entries:
