I babysit for my kids I live with, I need to do taxes. I read if I'm caring for a relative I don't need to self-employment, I enter the $ in the 1040 form, where/how?

I live with my adults kids and they give me money for babysitting my grand kids, I read that If I care for a family member I do not do self-employment but I do enter the income (as taxable) in the 1040 form, I just do not know where her in turbo tax I enter that.  even though the income is low I need to file for health insurance purposes. Thank you.
