According to TurboTax, and other sites, you do not need to report the sale of a second home (as long as it's not a rental, & meets the 2 year rule, & 250K/500K rule). The original poster didn't specify if this second home was in fact a rental. As far as a 1099S, we received one at closing and TurboTax still says we don't have to report. IMO, neither does the original poster (if it wasn't a rental)?
