The IRS has a program to do additional review of tax returns claiming te Earned Income Credit or the Child Tax Credit. Unfortunately, you are stuck while they do the review.
If you are experiencing financial hardship as a result of not receiving your refund, I recommend reaching out to the Taxpayer Advocate Service. These are IRS employees and they really work to resolve issues for taxpayers, especially when you are experiencing financial hardship.
You can find your nearest Taxpayer Advocate office here:
