Welcome to the Community, @accounting244.
The User View may be set as Business View which is why you're not seeing an option to create a journal entry in QuickBooks Online (QBO). If that's the case, let's change it to Accountant View. This can be done by going to the Account and Settings.
After that, go back to the + New button to continue creating a journal entry. For future reference, consider checking out this article: Create a journal entry.
I want to make sure everything is taken care of for you, so let me know if you have any other issues or concerns by leaving a comment. I'm always happy to help. Have a great day!
