It's been a while, but I'm back doing 1099Rs again. Does anyone know what should be put in Box 12 and Box 15? The IRS instructions say that these "boxes are provided for your convenience only and need nat be completed for the IRS." I was under the assumption that a distribution that is taxable at the state and local level should be in box 12 and 15. Thank you.

See the following site to get better answers. At the bottom is page numbers - box 12 is page 4.
