WHERE DO I ENTER SALE OF PRIMARY RESIDENCE?

Your home sale is reported under Less Common Income in the Wages and Income Section. 

Refer to the TurboTax Help article: Where do I enter Form 1099-S? for navigation instructions for TurboTax Online and TurboTax Desktop,

You may not have to pay taxes on the profits if you meet certain conditions.

The three tests that you must meet are:

1. Ownership - You must have owned your home for at least two of the five years before you sell your home.
2. Use - You must have used your home as a personal residence for at least two of the five years prior to the date that you sell your home.
3. Timing - You can't exclude the gain of another principal residence that you sold within two years of the current sale.

If you meet these requirements,  you don't have to pay taxes on the first $250,000 (500,000 if you are married and file a joint tax return). If your profit is more than $250,000 ($500,000 if MFJ) then, the excess is reported on Schedule D as a capital gain.
