We are new immigrant and 70+ years old, with no job, me and my wife living with my son but we are not his dependents. He give us $200 monthly for personal expenses and take care of food and shelters expenses. We just help him in domestically, like baby sitting when they out of some minor normal activities.

We have Affordable health care and received 1095-A from Health Insurance Marketplace.We already informed Affordable care about this $200 monthly income income from my son.

Questions are.
1- Do we need to mention this $200 per month in our 2017 tax return filling, if yes, what form(s)/document(s) my son need to provide us.
2- How we file/mention 1095-A in 2018 returns

Your input will help us to file 2017 return on time.
