Hello there, @Atas2020.
Let me share some information about the access of your employees in your QuickBooks Online account.
In QuickBooks Online, managing your employee's specific access to payroll is not yet available. You can only manage the user's access.
You can read this article for more information about managing the user and limit their access: User types and user permissions in QuickBooks Online.
I've also added an article to check the improvements and added new features to QuickBooks Online Payroll: QuickBooks Online Payroll price increase, and feature updates FAQ.
If you have additional questions, feel free to leave a message in the comment section. I'm always around here in the Community to help. Keep safe, and have a good day.
