I didn't claim my child last year but did this year. I sent my return on 2/19. It's still processing. I just rec'd the $1400 check but not for him. Will I receive that?

According to the new law, once the IRS processes the 2020 returns and if the result is a higher stimulus payment, the payment will be issued.
