SteamTrain, I believe that the 414(h) contribution is to be excluded from the amount in box 1 of the W-2. It would only get added back to the box 1 amount as part of the correction to the W-2 if the employer originally excluded the 414(h) amount twice, once correctly as the 414(h) amount to the 403(b) and erroneously a second time as part of the amount reported with code D in box 12.
