Yes, you can get the reduction in Federal income using Form DR 0104AD, line 8. As noted on the form, if you're not the 529 account owner, you need the account owner's name and SSN.
One point of clarification: The reduction in Federal income on your Colorado tax return solely applies to contributions made to CollegeInvest 529 plans. You cannot deduct contributions made to a tuition savings plan for another state.

It's usually on the page, in the state program, called "Here's the income that Colorado handles differently".
You will record it on your Indiana return. If your state is one of those states that will let you deduct all or part of your 529 plan contribution, TurboTax will prompt you to enter your contribution when you get to the credits and deductions portion of your state taxes.
I see no "Credits and Deductions" portion on my Wisconsin state returns. We do get a deduction for 529 contributions.
Each state return within TurboTax handles the 529 contributions inconsistently.
For Wisconsin, you need to look for a page titled, 'Here's the income that Wisconsin handles differently'. While on that screen, scroll to the Education section and click Start or Update beside College Savings Account. This is where you can enter your 529 plan contributions.
