Amana water dripping inside fridge

We have water dripping inside the refrigerator. I was told to clean the pan or something. I’m not sure what to do. I opened the flap at the bottom of the fridge in the back and don’t know where to start. Any help would be great. Trying to get this done myself do I don’t have to pay an arm and a leg.

Thank you :slight_smile:

I guess the better question is where is the defrost drain? And how can I unthaw it and clean it?
