Reporting income for babysitting my grandchildren

I am trying to report my income that my daughter paid me for babysitting her children in her home while she worked in 2021. She did not issue me a W-2 or 1099. No taxes were paid by either of us. She claimed the Dependent Care credit

 

IRS Publication 926 seems to say that I am exempt from paying self-employment taxes on the income since I am her parent, but I still don't know how to report the income on my taxes. I have been instructed from the chat tax assistants to report the income on a Schedule C, but according to the IRS Publication 926, it doesn't seem correct.

 

Any help is appreciated!
