ATTENTION : just because the IRS sent you a notice asking you to fill out and send in a form 15111 doesn't mean the TT program or you did anything incorrect. The IRS just believes that you "MAY" be eligible for an EITC based on something they probably changed on your return ... this happened a lot on the 2020 returns because of the unemployment exclusion that was implemented after many folks had filed.
If you get one of those requests respond as directed asap to see IF you are eligible for a credit.
