First I have included a screenshot of the worksheet to point out that the amount is entered several places. Line 1 shows the tuition amount and also what credits that amount qualifies you for, so it is repeated. This is not an error, since you may only choose one credit per student.
To edit the 1098-T and other education information on the desktop version:
Go into step-by-step mode
Click Federal Taxes and then Deductions & Credits along the top
Click "I'll choose what I work on"
Scroll down to under Education
On this screen you can see the total education expenses the program has computed
Click Update if needed next to Expenses and Scholarships (Form 1098-T)
The next screen gives you the option to Edit (please see second screenshot)
