You would consider this as bartering income, and report it on Schedule C.  With TurboTax open, type "Schedule C" in the Search box and then select the "Jump to" link to report this income.

The amount you report would be the fair market rental value of the place you lived in exchange for your services.

Please see TurboTaxAshleyR2's previous answer on point, below, and the IRS' Topic Number 420 - Bartering Income for more information.
