I'd be glad to walk you through how to locate the list of journal entries in QuickBooks Online (QBO), @mitchell-jrm.
When creating a Journal Entry, you have the option to view the recent entries by clicking the clock icon at the upper left of your screen. After that, scroll down to the bottom and tap View More. This will open up all the journal entries you created. Then, filter to search for specific entries. See the screenshot below for your visual guide.
Aside from that, you can also utilize the search function tool to find transactions in your QBO account. Check out this link for more details: Search for transactions using the magnifying glass.
Keep me posted if you require further assistance locating journal entries in QuickBooks. I'd be more than willing to provide the necessary help.
