The normal payments are not RMDs; they’re lifetime annuity payments. And all normal annuity payments from the beginning have been coded “Q”.
Box 2a taxable amount = $1,601.58. IRA type is not checked. So it’s contradictory.
An additional complication is that they withheld $160.16, even though I had previously set my account at no tax withholding.
I have just talked to TIAA about this, and they refuse to change the 1099-R or to refund the incorrect withholding. The explanation the phone rep gave me was essentially a lot of words communicating no reason for their stance, except that “this was a separate payment separate from annuity payments”.
At my request the phone rep’s manager is supposed to call me later this week.
