Start with a State hunting regulations pamphlet, or online. It’s likely only some parts of Idaho have a season open for Turkey. You can also look at online game distribution maps, may be a few years old.
Keep an eye on seasons for grouse & other species, backup.
You can also call up the State Fish & Game office, see what tidbits they may have. I see a lot of Western States have some type of ‘hunter access’ program.
