The only other way to be sure is to call the IRS. Their contact phone number can be found at www.irs.gov. They will answer your questions for free. I just called them a couple of days ago, since I was not sure if I had to file social security disability benefits for my daughter. They took me through a list of questions, and told me no.
Even if your daughter didn't make enough to pay taxes, she can still possibly get a small return for EIC (earned income credit) and child tax credit.
Actually she can go to turbo tax, and enter all the information in she has. Turbo tax will tell her if she is eligible to get a refund. She does not have to file through Turbo Tax if she does not want to. You only pay for turbo tax if you file through them.
