Bake the tater tots according to the bag instructions (place on a parchment-paper lined sheet pan and bake at 450 degrees Fahrenheit for about 25 minutes until crispy).
Meanwhile, in a medium bowl, mix the black beans with olive oil, garlic powder, chili powder, cumin and kosher salt. Chop the cilantro, red onion, green onions, and jalapeño pepper (if using).
When the tater tots are baked, sprinkle them with the cheese and place them back in the oven until it is melted, about 2 minutes.
Remove the tray from the oven. Top with the beans, cilantro, red and green onion, drained pico de gallo and corn, sliced jalapeno peppers (if using), and dollops of sour cream and guacamole.
