TPTK, what the hell do I do with it

[Greenfield]

20 euro NL at B2B. No reads.

One limper, I raise 4x BB with AQos from the CO, both blinds and limper calls. All stacks around 20 euros.

Flop is 9Q7 two clubs, I have the queen of clubs.

Checked to me, I bet the pot, one caller.

Turn is the 6 of diamonds, he checks, I bet two thirds of the pot, he calls.

River is the T of clubs. He pushes all in for the rest of my stack (6 euros), pot is 27 euros.

What do I do on the river and what should I have done on every street before that?

I am noob at NL and noob at posting here, so if I have done anything wrong, please berate me.
