Error message - Related Payment Activities "button"
The error refers to the old name of the Other Activities in the Payroll Center section, and the error message itself indicates that the liabilities you are paying do not have a payment frequency/schedule or lacks payment information such as an account number. Therefore, you're prompted to check them first. I will guide you to check them.
From the Employees menu, choose Payroll Center.
Choose the Pay Liabilities tab.
In the Other Activities section at the bottom, click on Manage Payment Method to check or assign schedules to your payroll taxes.
Click to highlight a tax with missing details, and choose Edit.
I've also taken notes about this, so our engineers can consider revising the message to take effect in future updates. You can also submit feedback by clicking on Help and choosing Send Feedback Online
