I am entering a 1098T but it won't let me enter anything under tuition and enrollment fees which I have an amount from line #1. It says I already entered it.

Since TurboTax has some of your data from the prior year, it is treating it as an item to edit, which will appear at the end of this section.  The best way to get this year's data into the program is to edit it following these steps:

To edit Form 1098-T, follow these steps:

1. Login toTurboTax.com.
2. Click on Tax Home on the left side of the screen.
3. If prompted, click on Continue where I left off or Take me to my return.
4. Choose Deductions and Credits from the top of the screen (for some users, this may be in the center).
5. Expand the Education section.
6. Click on Start (or Revisit).
7. Proceed through the entire education section answering all of the additional questions - you will go through about 8-10 additional screens, and then you should reach a summary page.
8. On the Education Summary screen at the end of the section, click Edit/Delete.
9. Edit your entries.

If you still cannot edit the data or you cannot get to the Education Summary screen, follow these additional steps:

1. Click on Tax Tools in the menu on the left of the screen.
2. Click on Tools.
3. When the Tools Center opens, click Delete a form.
4. Scroll down the list of forms and click delete beside Form 1098-T.
5. Confirm on the next screen by clicking Delete Form.

1. Scroll down the list of forms again and click Delete beside Education Tuition and Fees Summary.
2. Again, confirm on the next screen by clicking Delete Form.

This should clear the section out entirely and let you start fresh
