Hello, Dawn. To assist you better, could you please let me know if you have an active QuickBooks Online Payroll subscription? If you do, could you share any specific error messages you've encountered during the setup process?
Please note that an active subscription is required to access these features. If your subscription is active and you still can't access Payroll Core, I recommend contacting our phone support team. They can look into your account and provide the specific guidance needed to resolve this.
To get started, go to the Help (?) icon. Then scroll down to select the Contact Us button and follow the prompts. You will be able to request a callback or start a live chat with an expert. You can refer to this article for guidance on support hours: How to Get Help with QuickBooks.
Let us know if you have further questions. We're here to help you anytime.
