should I list $$ compensated for building a house? He does not have a business per say. If so, where do I list this on the return?

Yes - it is self-employment income, so he will need to set up a business form (Schedule C) in TurboTax.   He can use his own name and address for the business.   Enter the income and he will be allowed to deduct business related expenses to reduce the income.  

Where do I enter Schedule C?

What self-employed expenses can I deduct?

How does contract or freelance work affect my taxes?
