We need more information in order to answer your questions. First of all, so sorry for the troubles your family has had.
You have been helping your son who has PTSD with bills and living expenses--but you do not mention if he is married with a spouse who works. Is he married? Does his spouse have income? Will they be filing a joint tax return? Did he have ANY income in 2019? If so, what was the source of his income?
Your other son who is single had a couple of surgeries. Did he have income in 2019? What was the source of his income? Was it more than $4200?
Your own income is SS and retirement income from pensions and retirement accounts. Are you having tax withheld from that income?
