@Anonymous is correct; you need to prepare Form 6252 for each property and you need Forms Mode.
However, your profile suggests you are using an Online version of TurboTax and Online versions do not support Forms Mode. Therefore, in order to prepare your return, you will have to switch to a desktop (CD/Download) version of TurboTax.
