There was not a season 7 for The Sopranos. It had a season 6 that was split into two parts. There was talk of a movie after the series ended in 2007, but with so many characters dead (and, sadly, James Gandolfini's death in real life), it seems more unlikely than ever.
There were 86 episodes in 6 seasons. the last season being the shortest, was broken into 2, originally they planned on stoppping it after 12episodes but then they added an extra 6
