My sure the baby's name and social security number match what is on the social security card. You said that you have answered all the questions correctly and selected that the baby lived with you the whole year.
Delete the baby's information.
Make sure that you are using the Chrome browser. Go to the three dots at the top, select settings, then privacy and security. Clear browsing data for all time.
Enter the baby's information again. Make sure that the program shows that the baby lived with you all year in 2020.
Because both stimulus payments are an advance on the 2020 tax return, you will receive a stimulus payment for the baby for both 2019 and 2020.
