I’m trying to enter information from my 1098-T and I can’t find where to enter in my qualified tuition in order to receive the tax break

Assuming you've "been there, done that" and need to get back and change or verify it:

Go through the entire education interview until you reach a screen titled "Your Education Expenses Summary".  Click edit next to the student's name. That should take you to a screen “Here’s your Education Summary”. Click edit next to the section you want to change; tuition, in your case (click edit next to the school name)..

Details:

To enter your Form 1098-T information (even when TurboTax thinks it has already been entered and is showing $0), go through the entire education expenses section of your return until you reach the screen titled “Your Education Expenses Summary”, then follow these steps:

• Click Edit next to the student name.
• On the screen titled “Here’s your Education Summary”, click Edit beside Tuition.
• Enter the information from your Form 1098-T.

To go directly to the Education section of your return, use these steps:

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “education” (be sure to enter exactly as shown here) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to education”
• Click on the blue “Jump to education” link
