Depending on which model you bought - it probably came with an IC, MOD and Full......../ you can shoot those...or I would just buy the Browning brand of extended chokes and start with an IC and MOD...( I like Browning Midas grade ).
Every sporting clays course is different ...but I probably shoot IC and MOD 90% of the time. ( but I carry a Cyl, Skeet, IC, MOD, Imp MOD and a Full ) in my vest.
