I think you should have bet the turn just because you are so deep. You want to get all your money in.
Like every draw out there got there on the river (67, backdoor flush, maybe even 55 and TJ already got there on the turn)

I don't think checking behind on the river would have been bad. It seems like a blockingbet but he might just want to get a little bit more money from his real monster after you checked behind on the turn.

2-1 on your call is nice but I don't really think you can beat anything here.
