Get your taxes done using TurboTax

Do not add the 1099-MISC to your return.  Create a separate logon ID and password for your child and file a separate  return for her.  You can use the same emall address that you use for your TurboTax account.

You can use
TurboTax Free File for her return as long as she meets the income requirements.
 

On the Child's return be sure to check the box that says she can be claimed as a dependent by someone else.  That is VERY important.  Double check that.  
 

You will add the 1099-MISC in her wages and income section.  Answer the questions about the 1099-MISC. 

Finish and file the return.
