I am a federal retiree (not on Medicare) who has an HSA that receives premium pass through contributions (funded mostly by my former employer, the federal government) plus my own contributions. I successfully used this method to report the government contributions to the HSA. In my case, this was important since I am trying to clean up a minor amount of prior year excess contributions and Turbo Tax would not correctly identify the fact that I had excess contributions to withdraw without me figuring out how to input employer contributions that did not originate from a W-2. So thanks for the post...this worked for me.
