Q. So I would just need to have some way of showing that the amount I claim is associated with tuition?
A. Yes and No. No, because that money was included in your taxable income, it's your money to do with as you please. It doesn't matter for what reason your employer paid you that money*. Yes, you may need to show (if ever audited) that you paid tuition, to claim the LLC. So, yes you may need some documentation that you paid tuition. It appears that maybe you don't have an tuition statement, as such.
*The "standard no taxable part" is treated differently. That must be used for tuition to be tax free.
