Form 6475

My wife and I each received a form 6475 listing the amount for ourselves and our kids. The kids turned 18 in 2021. TurboTax is asking for the amount of recovery funds the now 18 years old received and is trying to add $1400 to their refund when I enter $0 since the kids did not recieve a form 6475. How do I enter the recovery funds for the now 18 year old kids and how do I enter it for myself and wife now that we do not have dependents?
