This 1099-R, as well as all previous, shows the account number of the immediate annuity, which is different from that of the Roth IRA from which it sprang.
I will try to get access to whoever produces the 1099-Rs. But TIAA’s official line is that deeming the correction payment taxable was deliberate on their part from the outset.
What do you think of the idea of using Form 8606, Part III to offset the taxable correction payment with Roth IRA basis? That could be a back-up in case Form 4852 doesn’t work. Or is Form 8606 not supposed to be used for immediate annuities?
If Form 8606 can be used for immediate annuities, then according to the instructions, I should have been filing it all along–but never knew I was supposed to.
