Add the 1/2 water, 4 crushed garlic cloves, and 1 tsp vinegar to the bottom of the Instant Pot. Place the metal trivet that came with your pot over the liquid.
In a small bowl mix the chili powder, oregano, cumin, onion powder, garlic powder, salt, and smoked paprika together.
Sprinkle ALL the seasoning over your cut chicken breasts, on all sides, pressing it in to make sure it sticks.
Place the seasoned chicken pieces in the Instant Pot on the metal trivet (note: As you pick up the chicken mop up any extra seasoning with the chicken pieces. Don't miss out on that flavor!)
Pour 1 cup of jarred salsa over the chicken, trying to keep it on top of the chicken and not in the bottom of the pot.
Pop the lid on the pot and lock the pressure valve to "seal". Set it to cook on Meat/Stew mode, on hight, for 7 minutes.Do a 7 minute natural release, then finish the rest of the pressure with a quick release. Place the chicken in a mixing bowl and add 1/2 cup of liquid from the bottom of the Instant Pot. (optional: add the garlic cloves too). Squeeze a little fresh lime juice over the chicken. Shred the chicken using a hand mixer (or stand mixer with a paddle attachment). You will want to do this while the chicken is still hot/warm.
Taste for additional seasonings (salt, pepper, or heat- cayenne or red pepper flakes), and serve in hard or soft taco shells with your favorite taco toppings!
