Place 1 cup of water in the Instant Pot and insert the metal trivet.
Position the ground beef on the trivet, seal the lid, and set to high pressure for 20 minutes (frozen) or 15 minutes (thawed). It will take about 7-8 minutes for the Instant Pot to come to pressure.
After cooking, perform a quick release of pressure. Transfer the beef to a bowl and remove the trivet, then clean the pot with soap and water.
Dry the pot and return it to the base, add the beef, and use the "sauté" function to brown the meat while breaking it apart.
Stir in the spices, salt, pepper, tomato sauce, and additional ½ cup water, and continue to sauté until the meat is cooked and liquid is reduced.
Serve the taco meat with your choice of tortillas or taco shells, along with your preferred taco toppings.
