Resolved:Form 8814 - Child Income "Learn More" Link Information Differs from Pub 929
Child income information in TurboTax was indicating the child's income had to be more than $5700 for the child to be required to file their own return.
However, the correct amount should be more that $5950 per Pub 929.
