You'll need to wait until you receive a notice from the IRS telling you of the changes that were made to your return.

There'll be a phone number provided that you can call, and also instructions on how to contest the change.

@JohnW152 is correct.  But let me add this:  It's possible that the IRS changed something else on your return (such as your income), so that your EIC also changed or was eliminated.  Could you have made a data entry error, or forgotten to claim some income?
