Working on taxes for my Grandfather who only has a government pension and social security for income. I have a CSA 1099-R and am not sure what the taxable amount should be. It currently says "unknown". Box 1: 39576. Box 2: Unknown. Box 5: None. Box 7: 7-Nondisability. Box 9: 28281. Should the taxable amount for 2a be the amount in box 1 or should it be box 1 minus box 9b?
