Normally my ex claims my son as a dependent although he lives with me full time. That's just how we set it up when we divorced, he claims one I claim one. However, this year (2020 taxes) he did not claim him for whatever reason. My son is 18 so he was excluded from the last 2 stimulus payments anyways. However, this one he is able to receive. So my question is do I need to amend my return to add him as a dependent for him to receive it; or do I need to file 2020 taxes strictly for him with 0 income for him to receive it? I cannot seem to find any information online to help me determine which route I need to go. Since mine were already filed, approved and refund received I would have to amend mine. I just don't want to mess it up for him to receive it.
