How to handle Car Loan Interest paid to me by my daughter

I loaned money to my daughter to buy a new car this year.  We agreed to the going rate at the time (2.5%), and I have kept records showing principle and interest payments to date.  Does she, or do I, have to create a 1099 for this, or do either of us have to send any paperwork to the IRS?  Once that question is settled, where do I claim in the interest in Turbotax?
