@Opus 17 - on #4, it's even narrower than written for AOTC; LLC is a different matter
Students are not eligibile for the refundable portion of AOTC if a) they are under 24 and not living independently AND B ) they are not orphans (either parent is alive) AND c) they file other than MFJ. ... so 8 permulatations and 7 of then maintain eligibility for the refundable portion of AOTC.... assuming they are not claimed as a dependent by someone else (otherwise, no eligibility).- the 'can be claimed' doesn't matter in this case.
Not sure where the $20,000 comes from. If there is a tax liability, there is eligibility for both the non-refundable portion of AOTC as well as LLC. (assuming not claimed by someone else).
