How do I list that I was covered by my parents for all 12 months, when my W2 reflects me being covered for 1 month?

To indicate that you were covered last year, while logged in and in your return:

• Cick on Personal tab
• Click on Health Insurance
• You will be asked "Did you have health insurance coverage in 2018?"
• Select "I had health insurance coverage all year."
• Click Continue
• Answer No to "Was anyone covered by any of these plans in 2018?"
• You should see "That's all we need on your 2018 coverage"
