Child Tax Credit

When I do my taxes on the TurboTax website, I get the child tax credit, when I do them on the locally installed version of TurboTax, it says I don't qualify.  I started doing them on my locally installed version, and when I saw I didn't get it, I did them online to verify.  Also, when I go to the IRS website, it says I qualify for the tax credit.  My TurboTax updated today, so it's up to date.  What is going on here?
