According to this article by Forbes – https://www.forbes.com/sites/jimwang/2020/08/07/did-you-get-a-second-stimulus-check-today-heres-why/#f4e6c4b299e0, there was a glitch that was corrected May 17, 2020 if you used the Non-Filers tool on the IRS website. The glitch didn’t count your 16 year old and under dependents.
Contrary to some claims I have seen on social media, this is not the second stimulus check as negotiations are temporarily deadlocked on the subject of a second stimulus deal. I expect the issue will be resolved in the near future. One thing I believe both sides are missing is the likelihood of at least one more stimulus check being needed after the second check gets passed. There’s always the possibility the economy will recover faster than expected, but there is no guarantee that will happen.
The IRS has updated its website to explain the delivery schedule and how it would be executed (Question 53):
“The IRS will automatically issue the additional $500 EIP per qualifying child to affected individuals in early August for those who used the Non-Filers tool before May 17, 2020. Direct deposit payments are scheduled for August 5, 2020, and paper checks or debit cards are scheduled to be mailed August 7, 2020. You can use Get My Payment to check the status of the $500 EIP per qualifying child, and you will receive another notice in the mail letting you know the $500 EIP per qualifying child was issued.
If you received your EIP by direct deposit, the additional $500 EIP per qualifying child will be direct deposited to the same bank account.
If you received your EIP in the mail, the additional $500 EIP per qualifying child will be mailed to your address of record.
