That's a LOT of social security.... is it for prior years?

And if the dependent received it, under their SSN, then it goes on THEIR return.

If it is for back years, you can 'average' a lump sum distribution (see link to a recent thread below) .... but if it is for the dependent, is any of it actually taxable?
