Did you have self-employment income or income from a 1099-NEC? If so, this would be why it is asking for the Schedule C. You do not have to own a business to file a schedule C. You can work for someone that pays you for something like mowing the grass or babysitting. Then you would need to include that as self-employment income.
Being a student does not exclude you from being self-employed.
