Turn on the yogurt setting (normal heat) on your Instant Pot.
Pour warm water into your Instant Pot inner pot. Stir in sugar until dissolved. Sprinkle yeast on top of water and let activate for about a minute.
While yeast activates, mix together flour, salt, garlic powder, and Italian seasoning.
Once yeast activates, mix in flour mixture. Form a fairly stiff ball of dough (sprinkle in extra flour if needed). Pour half of the olive oil over the top and rub over ball.
Allow dough to proof in Instant Pot for 30 minutes to an hour. Dough should rise to about double volume; poke down with a fork if needed.
Once dough rises, remove from Instant Pot and kneed in extra oil (and a little extra flour if needed to make the dough more firm - it should not really be sticky). Spread into one very big pizza or 4 personal-sized pizzas and bake dough at 350 degrees for 6-8 minutes. Add toppings and bake for an additional 12-15 minutes to finish pizza.
