Form 8862 is the form the IRS requires to be filed when the Earned Income Credit or EIC has been disallowed in a prior year. If
your EIC was disallowed or reduced for reasons other than math or
clerical errors after 1996, you may need to file Form 8862 before the
Internal Revenue Service allows you to use the credit again.
The video below explains how to add the form to your return in TurboTax.
