I'm trying to enter 1098-T but not finding input section. Then, it tells me that I've already entered -0-. Frustrating!!+

Oh, yes! The zero tuition shows up early and you have to keep going until you are able to edit. If you have numbers in boxes 1 and 5, I am also going to recommend you look at another of my answers for help.  

Follow these steps:

1. Did you pay for books or materials to attend school? Yes
2. Enter related amounts, tuition will say $0
3. Continue
4. Scholarships and Financial Aid, continue
5. Did you get a scholarship? yes and fill in boxes or no
6. Continue
7. screen asking Four Years of College Credit Before 2019? answer yes or no
8. Continue
9. Is this First Year of College? answer yes or no 
10. Continue
11. Ever Receive American Opportunity or Hope Credit? answer yes or no
12. Continue
13. Felony drug conviction? yes or no
14. Continue

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).

This worked but I think turbotax could reorder the questionaire. Thanks for both replies!
