Can someone please explain certain numbers in a TurboTax Student Worksheet?

[dyons]

I attach  an image at the bottom of this post of a relevant part of my student's information worksheet related to education expenses.

The input numbers (provided via the interview process) are:

Tuition and related expenses: 42,518

Book: 128

Room and Board: 12,522

Scholarship: 16,000 (non taxable)

When I look at the generated Student Information Worksheet (image attached at the bottom) I cannot understand the number $14,124 in item 18 "Use for exclusion" in the column for AOTC. I don't know how it was arrived at. I thought it should be $4000/-, the exclusion for taking the AOTC (just as it is for the 529 plan - see three columns over).

Please can someone explain how this number ($14124)  was arrived at?

Any help would be appreciated.

I can;t figure it out either, but it really doesn't matter, expenses for AOC are capped at $4000 in any event

look at line 27 for the IRS form

Thanks for your response @NCperson and apologies for my belated reply.

Yes, I do realize that the max cap on AOTC is 4000/- and, indeed, on another child's student worksheet, the number in row 20 ("Adjusted qualifying expenses") is 4000/-

While it does not make any practical difference to the overall credit obtained and the form filed, it worries me that there is a calculated number in a worksheet which cannot be adequately explained.

Is there a way to get TurboTax to respond to this issue? Or are there other members in the community who also have this problem?

Thanks again.
