Do I put health benefits in box 15 of my 1099-R, as my employer does, even though in TurboTax box 15 is designated for local tax withholding?

In the 1099-R provided by my former employer (US Department of State), Box 15 is used to list my "Health benefits."  The model 1099-R provided by Turbotax reserves this space for local tax withheld (I have none).   Do I enter my health benefits here anyway?
