Hi there, manager.
I'll show you how to access your previously entered Journal Entries in QuickBooks Online.
To review previous Journal Entries in QuickBooks Online, we can utilize the Audit Log report. It provides a comprehensive record of all activities and changes made within your QuickBooks Online account, including Journal Entries.
Here's how:
- Go to the Gear ⚙ icon and select Audit Log.
- Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
- In the Events filter, select All transactions.
- To open the transaction journal, click on the hyperlinked text for the Journal entry.

I've also added this article as a future reference about the Audit log report: Use the audit log in QuickBooks Online.
