I'm trying to find out the name of a game show that aired on USA
Network,lasted 1 season,took place on a set that
resembled the Brady Bunch house.  Any ideas?

Hello.

I believe that the game show was the USA Network's "Smush."

"..So what on earth is Smush? It's a party game crossed with a game
show. Ken Ober, of MTV fame, hosts. The studio audience sits on the
stage (which intentionally resembles the Brady Bunch living room)..."
