How do I add another child on form 8862?

Are your other children Qualifying Children this year?  Did you enter all of their information, including Social Security Numbers and dates of birth and answer all of the questions to show you can claim them this year? 

You likely need to go back into the personal information section to correct the information so you can add them to the form. 

This worked!  I had the app open on two devices.  I had to reset the form under my info.
