Mix together the olive oil and spices in a small bowl.
Prepare the chicken by removing any gizzards from the cavity, rinsing in cold water, and patting dry.
Brush the wet rub onto the exterior of the chicken.
Place the metal trivet into the base of the Instant Pot. Add 1 cup of water. Place the chicken on top of the trivet. Secure the lid and set the valve sealing.
Push the Pressure Cook button and set the time for 18 minutes (see guide in post for other sizes).
Allow the pressure to naturally release. Test the internal temperature to be sure it has reached 165° F(75°C). Remove the chicken from the Instant Pot and serve.
Notes
You should cook the chicken for 6 minutes per pound, so if you have a chicken that's larger than 3lbs, be sure to set the temp properly.
If your chicken is frozen, cook for 8.5 minutes per pound and always check that it's up to the proper temp after cooking.
Rest the chicken for 10-20 minutes before slicing.
You can crisp up the skin of the chicken under the broiler for 5 minutes.
