I deleted an employee earlier this year who no longer worked for me. I recently added them as a new employee and created a paper paycheck for them. They are "active" in payroll, however when I search for their name, it appears as "deleted." 

I received the following payroll sync error:

• You can’t modify transactions for deleted employees. If you didn’t mean to delete them, restore the employee and then modify. If you did mean to delete them, undo the transaction.

How do I restore an employee?
