Didnt get the whole amt of their stimulus check or feel that there was a problem. You might want to check up on this one.

For some taxpayers, a second stimulus payment will not be a mistake: The IRS will be mailing out about 350,000 additional checks starting in July to taxpayers whose original stimulus payment did not include a payment for their eligible child.

"In some instances, taxpayers did not check the proper box to trigger the $300 child payment. In other instances, a few tax software products primarily used by tax professionals did not capture the proper information needed for issuing the child stimulus payment," the tax agency said.

"To fix the problem, the IRS is taking extra steps to identify the affected taxpayers and send them separate checks to cover their qualifying children. The IRS emphasized that the corrected checks will be mailed automatically, and taxpayers don't need to call or take any additional steps," the statement said.
