Go back to the personal info section and click edit next to your name. Go thru whole personal info interview. Because you are under 24, you will encounter a question: did you provide more than half your own support with earned income (or some such wording). Be sure you answered correctly.
The AOTC appears in two pieces on the tax forms. The $1000 refundable portion on line 29 of form 1040, The remainder ( should be $1500 in your case) will be included on line 20 of form 1040 (transferred from line 3 of schedule 3 and line 19 of form 8863).
Still, $1299 is a weird number. You may also have errors in entering your educational expenses. Check line 27 of form 8863. It should be $4000.
