Q. Can i also enter it into my daughters tax return with the hope of using the remaining $1500 from box 1 to offset taxes that she owes (from unearned income from some capital gains on an UGMA).?
A. Yes and no. No, in your case. One student means one tax credit and you've already claimed that, on your return. So not it cannot help reduce taxable income from a UGMA account. See answer to next question, for when yes might be the right answer.
Q. Can I claim the cost of a computer for my daughter , on my daughters taxes?
A. Yes and No. Although a computer is (almost always) a qualified expense, for the education credit, only one credit per student is allowed and you already claimed it. However the computer is also a qualified expense for tax free scholarship, so you (usually) might want to enter it (answer yes when asked if you have book expenses). But, in your case, you student already has $1500 of "left over" tuition to offset her scholarship and keep it tax free. But, again, those educational expenses are no help against UGMA unearned income.
