Thanks for clarifying, finance69. 

After we set up the employee's worker's comp information, the class codes and rates are shown under the each state's payroll settings. When we go to the Gear icon > Payroll Settings > Tax Setup, another section for each state is listed as XX Workers Compensation Tax once you've setup an employee under that state. You can refer to the screenshot below for your reference. 

If you're not seeing these options I suggest getting in touch with our Payroll Support Team. They'll walk you through on how to edit those codes and will sort things out with you. 

1. From the Help icon, click Contact us. 
2. Enter in the box something like Edit Workers Comp codes and rates. 
3. Click Let's talk. 
4. You can Chat, Call, or Get a callback as way on how to connect with us. 

I'm here to help you if you need anything else. Thanks!
