Here is how you can find the entry area for your 1099-Q: navigate to Deductions & Credits then select Deductions & Credits Summary, scroll to Education, click to expand it, then you can select ESA and 529 Distributions (Form 1099-Q).
Don't forget you can use these funds on expenses other than tuition, like a computer, supplies, and room and board. Publication 970 has further details on the types of additional expenses you can use these funds for.
