529 contribution for Colorado for tax year 2024?

Since 529 contributions are only deductible for state, not federal, you can directly go to the state taxes section of TurboTax Online.

Here's how:

1. Navigate to the left side of your screen once logged in, go to State Taxes > Your State Returns > Colorado > Start or Continue

2. Continue until you arrive at "Here's the income that Colorado handles differently"

3. Scroll to Education, 529 CollegeInvest Program Contributions, start or continue to claim the deduction.

In fact, 2024 TurboTax Deluxe for Colorado does not have a section about "Here's the income that Colorado handles differently."  I got around the problem by going to "Forms", pulling up the Form 104AD, and entering the 529 contribution there.
