I have an adult dependent (child) that is not required to file taxes for 2020 but will in order to file for the COVID stimulus payments. While there is no tax deduction for me for this child (not disabled), can I still include this child as a dependent in order to positively impact my MAGI calculation for the Affordable Care Act credit in 2020? The child had only dividend income for 2020. If I can include the child would I need to include that include on my tax filing and would they also need to record that they were claimed by someone else?
