Heat oil in a large stockpot over medium-high heat. Add onion, carrot, and garlic; sauté 5 minutes. Stir in 4 cups water and next 12 ingredients (through tomato paste); bring to a boil. Cover, reduce heat, and simmer 25 minutes or until carrot is tender, stirring occasionally. Stir in vinegar and chipotle. Top with fresh cilantro, cheese, and sour cream.
