Delete the 1098-T and re-enter. Go through the entire education interview until you reach a screen titled "Your Education Expenses Summary". Click delete next to the student's name. You'll then get the "Your Education Expenses Summary" screen again. Click the "Add a student" button.
What are you trying to accomplish (why are you entering a 1098-T)? Are you the parent or the student? The parent usually claims the tuition credit for a student-dependent.
The 1098-T is only an informational document. The numbers on it are not required to be entered onto your tax return. However receipt of a 1098-T frequently means that the parent (or the student) is either eligible for a tuition credit or possibly the student has taxable scholarship income to report.
