I've received three Form 1099-Rs for mandatory minimum withdrawals (age
70+) from my TIAA-CREF IRAs.
Two are small, and check out OK against quarterly statements.
But the gross amount (Box 1) for the third and much the largest withdrawal differs by $99 from the withdrawal amount shown in the relevant 2007 quarterly statement from TIAA-CREF -- and has an entry for $317 in Box 5, "Employee contributions/ Designated Roth contributions or insurance premiums".
I can't find anything in my quarterly statements explaining either of these amounts, so things don't seem to quite add up here. What's Box 5 all about?
