Preheat your oven to 350°F and lightly coat a 9x13-inch baking dish with nonstick cooking spray.
Microwave the cream cheese in 15-second intervals until it's very soft and easy to stir.
In a large bowl, blend the softened cream cheese, sour cream, and salsa until smooth. Fold in the shredded chicken.
Warm the tortillas as the package label directs so they're pliable and ready to roll.
Spread about half of the enchilada sauce evenly in the bottom of your prepared baking dish.
Spoon about ½ cup of the chicken mixture onto each tortilla, add a tablespoon of cheese, roll them up tightly, and place seam side down in the baking dish.
Drizzle the remaining enchilada sauce over the rolled tortillas and sprinkle with the remaining cheese. Cover with foil and bake for 30 minutes. For a golden top, remove the foil during the last 5 minutes.
