One confusion is that in certain circumstances, even though the children/dependents may have to "file" their "own return," this can be entered on the parent/guardian's return using Form 8814. So, although the child "files" own return, it is done in the parents' return. So, my child did file a return, but in our return on Form 8814.
A second confusion is that TurboTax says you must put the information from the 1098-T in the return even though it is not actually required by the program nor the IRS (thanks for TurboTaxChristinaS for explaining that detail). This seems like something the company might want to address in their explanations.
A third confusion is in the problematic tax law. A student who uses the scholarship to pay for housing (often required by the college at least for 1st year students; and, in practice required for anyone who does not live in the college's town) and food (gotta live). So, where does the student find the "left over" funds to pay the tax bill on the scholarship? -- the tax law should address this issue by including room and board as acceptable expenses and/or make scholarships un-taxed.
