Hello there, Beths.
Let me share some details about how the journal entry function works in QBO.
Firstly, may I ask if you want to delete it instead of turning it off?
In QuickBooks Online (QBO), having the option to turn off journal entries isn't possible. These are transactions wherein QuickBooks will make an automatic journal entry if you make tax payments, run payroll, and corrections like voiding paychecks.
Additionally, it is not a feature that you can turn off automatically.
Furthermore, I've added a resource you can browse through in case you need assistance on how to reverse or delete a journal entry entirely: Reverse or delete a journal entry in QuickBooks Online.
Let me know if you still have further queries managing journal entries or anything else about QuickBooks. I'm just one click away to assist you. Stay safe.
