TT says I qualify for American Opportunity Credit $2500 but worksheet only is giving me $1500... why?

There are two parts to the American Opportunity Tax Credit (AOTC). The credit is split out in two different places on your income tax return.

The first is a maximum nonrefundable credit of up to $1,500. The nonrefundable credit can be up to $1,500, . 

• It is on Form 1040 line 50 Education credits from Form 8863, line 19. 
• A nonrefundable credit is subtracted from your income tax liability, up to the total amount you owe. But unlike a refundable tax credit, a nonrefundable credit cannot reduce your tax balance beyond zero.
