Is there another way to enter the employer’s contribution to an HSA other than via the W-2 recording?

I am retired, age 67, receiving a pension and on Medicare. My wife and two daughters have medical coverage through my previous employer; a High Deductible Health Plan with a Health Savings Account (HSA). Contributions to the HSA to date have only been made by my previous employer. Turbotax is asking if my wife has put any money into an HSA during 2016, pointing out that this includes everything your employer contributed too. If I answer yes (due to the employer’s contribution) the next page that pops-up is prefilled with $0 for the employer since it is a W-2 reporting item. In our particular case, there is no W-2, since I am retired. Since I have recorded info from the Form 1099-SA we received reflecting a gross distribution it would appear to be problematic to have Turbotax reflect $0 contributions to the HSA. Is there another way to enter the employer’s contribution other than via the W-2 recording?
