We _are_ digressing! The original question identifies her son/dependent/student without other taxable income. The 8814 applies if no wages, no withholdings, _AND_ "gross" less than $10,500. I'm not at all clear if the scholarship for room and board adds to the "gross".
My current worry is that with my daughter's $4000 of at-schoolwages and summer job (out of state, to boot.) stipends added to imputed-income of room and board (which total rules out the 8814 option) the line regarding "more than half of her support" may also get crossed and she would no longer qualify as my dependent. (This circles back to the original question part (3) "can I claim him as a dependent?" )
This is a combined parent/dependent issue and I don't see how to get the TurboTax software to help me address the combined money flows. It seems I have to do a bunch of worksheets and decision-making before I even click on the menu to "Open New Tax Return" for my 19 year old.
