I bought my sister & brothers share of mom's home we inherited. I got a 199-S. What do I claim it under, second home, everything else or purchase?

The 1099-S was probably generated to reflect the home sale.  You sold 33.33% of it so treat it just like a sale of any asset like a stock.  Your basis is one third the fair market value at the time of death and you sold it for presumably the same amount so there will be no taxable gain.
