I think that folding to the check raise and overcall on the river is probably correct.

Your reason for calling down after UTG's flop cap, was presumably in the hope that he was overplaying a weaker Ace, plus a few outs to improve if behind to a 2 pair hand.

When SB check raises the river after having just called all the way, I doubt that your TPTK is good. Also as UTG has called you will at least see what the best hand was.
