This is as clear as mud.
My understanding is if you normally contribute money to your HSA through your employer, for example, a regular amount taken from your paycheck, this is not what they're looking for on line 2. Line 2 is for the money you are contributing directly to the HSA, not through your employer, not withdrawn from your paycheck.
I hope I'm right. I didn't contribute anything other than my biweekly contributions from my paycheck through my employer, so I'm entering $0.
