I've got your back, @dylans-cwmdonkin.
You may have the Employees menu in your QuickBooks Online (QBO) account that's why there isn't a Payroll option. You can click Employees from the left menu, then start setting up your payroll account from there.
You might want to check out this article to know more on how to get started with QuickBooks Online Advanced Payroll: QuickBooks Online Advanced Payroll hub.
Please know you can continue to reach me here with any additional concerns you may have about payroll. Thanks for coming to the Community, wishing you continued success.
