Clergy Social Security Exemption on Honorariums

I am clergy with Social Security exemption. I understand how this works with my primary income. However, on honorariums that I receive, I need to report those for income tax purposes (on Schedule C, I understand). However, since this is clergy income, I am not responsible for Self-Employment tax on this honorarium - but I don't see any way to exclude this added honorarium income from SSA tax. 

 

How do I do this?
