How do I fix My child’s W2 went as mine income. The other child also works in same place, so his W2 looks the same…

You should amend your return (if you already filed) to remove any child's w-2.   If your child(ren) have their own w-2s, they report those on their own tax returns.  

If you have not filed your return, search for W-2 and use the jump to w-2 link to get back to your W-2 summary where you can remove his w-2 from your return.   If your return was already filed and accepted, see this TurboTax FAQ for amending instructions.
