1) Section 179 only applies if your rental rises to the level of a "Trade or Business". Does your rental activity rise to that level?
2) Because it is most common that rentals for TurboTax users do NOT rise to the level of a "Trade or Business", TurboTax assumes it does NOT qualify, so it does NOT add the income to that section on Form 4562. If the rental does qualify, you need to override that amount on Form 4562 (which can only be done using the CD/downloaded version of TurboTax).
