The amount reported in box 2 of my HSA 5498-SA is indeed reported on my W-2 box 12c with code W. This would validate the comments that we do not need to enter the 5498-SA info separately, as this would be a double entry.
While we are on the topic, for what it's worth, I also received form 5498 "IRA Contribution Information", with a letter attached from the broker telling me it is also for informational purposes, and is a record of any deposits made to be kept with my tax documents.
