You say they are receiving "retirement."   Do you mean they receive Social Security?   Or are they also receiving some other kind(s) of retirement income like pensions, distributions from retirement accounts, etc.?    That matters.   And it matters whether you are providing over half their support -- so along with the issue of their income---are you paying for over half their support?   Provide some details.
