Payroll tax code for a higher education loan program

Hi MYOB support team,

We have a new employee who has a higher education loan program. I try to select the tax code with "HELP" but there is not in the tax table description list. How can select the correct one for it. I see there are some with " STSL" and not sure what these means.

Could you please someone help me for solve this issue?

Thank you very much.

Sherry
