You've come to the right place, @elizanndem. I'm here to lend a hand with determining who made the journal entry.
Just to clarify, are you looking in the Audit Log for when the transaction is dated? If so, this tool will sort changes based on when they were made and not on the transaction date. It will also display journal entries.
If you're unsure of when this journal entry was made, I recommend looking at the Audit History of the transaction. Here's how:
- Open up the transaction.
- Click More at the bottom of the screen.
- Choose Audit History.
From this screen, you will be able to see information about this transaction, such as who made it and the date. I've included a brief video to serve as an example:

For additional insight into the Audit Log, such as what information is tracked, please see the following article: The Audit Log: What it is, how to use it.
I'm confident that with this, you'll be able to determine the needed information about the transaction.
Should you need anything else, please don't hesitate to let me know. Best regards.
