Turbotax only gives 20 for American opportunity credit but hand calculations show much more. Why?

[TaxGuyBill]

Three things come to mind:  (1) you made a mistake in your hand calculations,  (2) you mis-entered something into the program, (3) there is an error in the program.

I haven't heard anybody else comment about an error in the program, so most likely it is one of the first two options.

Without knowing all of the details, it would be impossible for anybody to tell you much more than that.

• To claim the full credit, your MAGI, modified adjusted gross income, must be $80,000 or less ($160,000 or less for married filing jointly).
• You receive a reduced amount of the credit if your MAGI is over $80,000 but less than $90,000 (over $160,000 but less than $180,000 for married filing jointly).
• You cannot claim the credit if your MAGI is over $90,000 ($180,000 for joint filers).
