Where do I enter my ECN number?

I was trying to find out where to enter my ECN Number. I am on the Health Insurance Tab and when I select "I did not have Health Coverage at all in 2016" I just get hit with "Based on your situation, the penalty has been waived!
This means your taxes won't be affected for not having health insurance in 2016."

Does that mean the they won't need the ECN number?

The ECN is the Exemption Certificate Number.  If the penalty has been waived, most likely due to your income level, the ECN is not needed.
