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.
