Select 'Saute' and add oil to inner pot of Instant Pot.
Add sausage, and cook until browned, about 5 minutes. Break up the sausage if the pieces are too large. (If the sausage browns too quickly, press 'Cancel' until the Instant Pot cools down a bit and select 'Saute' again.)
Add onions and garlic. Stir until onion is translucent.
Deglaze pot with white wine, stirring until liquid has nearly evaporated.
Turn off Instant Pot.
Stir in bell peppers, sugar, dried basil, oregano, salt, black pepper, and broth or water.
Add in the tomatoes and pasta. Don't stir but just gently push down to submerge in the liquid.
Close the lid and pressure cook on High Pressure for 5 minutes.
