Millions of families across the country received the second round of child tax credit payments, but due to a technical issue, about 5 million are still waiting, including one Valley family.

Crystal Rosado, a mother of four, spent days creating a back-to-school shopping checklist preparing to send her kids back to campus for in-person learning.

But her shopping was put on hold after she found out that the IRS had not deposited her second child tax credit check on Aug. 13.

When she checks the IRS Child Tax Credit Update Portal online, Rosado says an error message pops up.

On Friday, the U.S. Department of Treasury issued a press release stating that a small percentage, less than 15%, of recipients who received payment by direct deposit in July will be mailed a paper check for the August payment.

That 15% translates to roughly five million families, including Rosado’s family.

IRS spokeswoman Irma Treviño says the issue will be resolved by September, but affected families like Rosado’s could wait up to four weeks to receive a paper check in the mail.

“If it does come in four weeks,“ Rosado said. “I will be so blessed.“
