Business & farm

A follow up question on this:

 

I'm in a similar situation: we own an Etsy shop, but it's actually my 15 yo's business, she's the one who created the products and answered customers' questions. However since she's a minor, all the legal/finance info is under my name. 

 

Is there anyway for parents to generate W-2 so that the child has an earned income so she can open a custodial ROTH IRA?

 

Thank you.
