I inadvertently selected an employee to be paid that shouldn’t be paid. How do I get the employee off the Time Cards, and out of this payroll run?

Go to the Data Entry tab and select Add/Edit Time Card Earnings and Deductions. Select the employee, then click on the Earnings radio button. Press Ctrl (on your keyboard) and the minus sign (located on the numbers row). Press Ok to confirm the deletion. Do this for all the earning records and deduction records. The employee will no longer be part of this payroll.
