Hi paul-chillibanan, thanks for posting on the Community
In QuickBooks Core Payroll, there are no longer payroll journals; instead, separate payments called 'payroll payments' will be recorded.
These will be found in the chart of accounts that were selected to map the payments to. You can manage these accounts by going to the payroll settings - account mapping.
For a helpful list of articles and step-by-step instructions, visit our Core Payroll Resource Hub. I'm just a post away if you have any further questions.
