If I worked multiple jobs in the food/beverage industry, how do I correctly report/calculate all the tips I made so I won’t get taxed on that?

I worked in 3 separate food/beverage businesses. It’s pulling my reported tips from one of those off of my federal return for my state return, but it’s not pulling the other 2. It’s saying MT doesn’t tax reported tips so I want to make sure I have it all correct.
