Okay, they are divorced and you live with your mother. That means your mother can claim you as a dependent (the scholarship does not count as you paying for yourself). That means the "Kiddie Tax" is based on your mother's income and tax bracket (which sounds like it may not be particularly high). If you can not get your exact mother's income on her 2017 tax return, you can enter an estimate (perhaps estimate a little high).
Unless your mother has very high income (which sounds like is not the case), you won't owe any tax (assuming you 'force' the extra $2000 of scholarships to be taxable, so you qualify for the American Opportunity Credit).
The program will ask for your mother's income to determine your tax, but as I said before, if you can't get an exact amount, give an estimate. As for the 'forcing' of the extra $2000 of scholarships to be taxable, perhaps
@Hal_Al could guide you with that. Otherwise, you could go to a tax professional.
But again, assuming your mother does not have very high income and that you will qualify for the American Opportunity Credit, you will not owe any tax.
The rules for "Kiddie Tax" changed for 2018, so if you have a similar situation for 2018, you will NOT need any information from either one of your parents for 2018.
