Why can't I enter my 1098-T? It's keeping my tuition and expenses at $0 and won't let me enter the actual amount. The prompt says that I already entered it.

Delete it and re-do it.

From the Left menu>Federal>Deductions & Credits>(All tax breaks>scroll to Education>)Expense sand Scholarships (form 1098-T) click Edit/Add>At the Your Education Expenses Summary click Delete.

 

When you re-do the Form 1098-T entry, follow these steps:

from TurboTax Expert KittyM:

STEP 1.) It will skip to books and supplies. KEEP GOING. You can't jump to, you can't hit back KEEP GOING as though you have entered.

STEP 2.) Do NOT put in scholarship amounts when it asks if the scholarship is listed on Box 5 of the 1098-T because you are about to double up. KEEP Going. you are about to circle back.

STEP 3.) Go through all screens. If says can't maximize because no expenses do not fret, Go all the way until it circles back to the Wages and Income screen.

STEP 4.) Go back into Education credit and hit Edit on the student. Will ask if you had education credit.

STEP 5) Once you do you may see the Summary Page of the student. Hit edit on the top one that reads Tuition.

Step 6.) Will ask if you had a 1098-T you say yes, and THERE is the 1098-T

There is no left menu.

I had to go back and take off the scholarship amount that you mention in step #2.

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.
