I assume that the 1099 you received is a 1099-S. There is no place to enter a Form 1099-S itself in TurboTax. Entering the sale of the home is all you have to do. Make sure that the sale is shown correctly on Form 8949. Other software may handle a home sale differently.
I would suggest entering the home sale in the Step-by-Step interview rather than in forms mode. The Home Sale Worksheet can be complicated and error-prone.
