Flopped flush, forced to fold on the turn.

Flopped the flush, and got 4 callers on the flop of the pot sized bet. I felt the most likely hands to be calling with in that situation were the ace high flush draw, a set looking to boat up, or maybe two pair. . Folded when check raised all in on the turn after the board paired. Any advice on the hand?
