What do I do, then? I've already filed. And if you're recommending that I amend my return, How do I remove the EIC? I didn't see any option to do that. And to clarify, the TT system clearly asks, at the beginning of the taxes, if you've had a child or a new addition to the family, during the past year. I answered "yes," of course, so I'm not sure what I did wrong.
