Form 8863 is used to calculate education credits. It is used for both the American Opportunity Tax Credit and the Lifetime Learning Credit. The Lifetime Learning Credit offers 20% credit for the first $10,000 of qualifying education expenses.
Regarding Form 8917 for the Tuition and Fees Deduction, this is calculated "above-the-line," which reduces income. The adjusted income is eventually taxed. In contrast, the credit is subtracted directly from taxes owed.

There are different requirements for the American Opportunity Tax Credit versus the Lifetime Learners or Tuition and Fees deduction.
Perhaps you took the AOTC 4 times already, or you are not an at least half-time student.
