A good resource for checking salary expectation is glassdoor.com. Here's a broad example of IT in Indianapolis. You can further add more specific options to fine tune it or check in other cities/job titles, etc.
I do have to say though that the major decision maker for a career should not be salary. Of course it is important but you can find stories of people not liking their job and a high salary not being worth the unhappiness. There's a reason that there is a saying "do what you love and you'll never work a day in your life"
Realistically for many millennials with student loans to pay back, a strong salary is important but remember that a working career is commonly 30+ years so balance long term plans as well.
Fortunately the IT field is a large, diverse, and growing field so there will be opportunities to find something you enjoy, you're good at, and provides well. Stay positive!
