Meanwhile, cook celery, carrot, onion, and garlic with chile powder and 1/2 teaspoon salt in oil in a large heavy skillet over medium heat, stirring occasionally, until softened, about 10 minutes. Add to bread-crumb mixture with turkey, dried apricots, parsley, 1 tablespoon preserves, 1 tablespoon soy sauce, Worcestershire sauce, eggs, 1 1/4 teaspoon salt, and 1/2 teaspoon pepper and mix with your hands until just combined. Form into a 9- by 5-inch oval loaf (mixture will spread slightly) in a 13- by 9-inch shallow baking dish.
Stir together water, remaining 2 tablespoons preserves, and remaining 1/2 tablespoon soy sauce and brush over surface of meatloaf. Bake until an instant-read thermometer inserted into center registers 165°F, 1 to 1 1/4 hours. Let stand 10 minutes before serving.
