You will need to enter two different Self-Employment activities.

You will report your business on its own Schedule C.
You can then add another Schedule C to report the housing allowance for your spouse. Your spouse should have received a W-2 Form. Make sure to select that they are a member of the clergy. TurboTax will walk you through the steps and will ask for your housing allowance once you mark this box.
