Which option do I chose for self-employment tax for clergy?

I'm having trouble knowing which option to select for self-employment tax for clergy. I receive mainly housing allowance from my employer. They withheld money throughout the year from my housing allowance for "self-employment taxes." I just don't know which of the options to select:

1. Pay self-employment tax on wages only

2. Social Security and Medicare taxes have been withheld

3. Pay self-employment tax on housing allowance only

4. Pay self-employment tax on wages and housing allowance 

Option 5 doesn't apply to me.
