Hello there, @angelina21.
Let me share some insights about why are the Workers Compensation section are greyed out in QuickBooks Desktop (QBDT).
In QDBT, you'll need to set up the workers' compensation before you pay your employees so your reports won’t be incorrect or incomplete. However, the Workers Compensation feature will only be available if you have an active payroll subscriptions. With that, you'll need ensure your payroll subscription is active and you have the appropriate access in the Company file.
Once the feature is activated, you can directly set up Workers Comp for your employees and their class codes. To learn more, visit this article: Set up manual Workers' Compensation in QuickBooks Desktop.
Additionally, I'm leaving this article for future reference if you want to run some of the available workers' compensation report in QBDT: Troubleshoot Workers’ Compensation report in QuickBooks Desktop Payroll.
Should you have other questions about Workers Compensation in QuickBooks, please let me know. I’ll be happy to assist you further.
