You will need to indicate that you had High Deductible Health Plan (HDHP) coverage at some point during the year in order to be eligible to have contributed to a Health Savings Account (HSA), otherwise your entire contribution is considered to be an excess contribution. 

Use these steps to go back through the Health Savings Account (HSA) section of your return to answer the questions and verify that you were eligible to contribute to the account: 

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “hsa” (be sure to enter exactly as shown here) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to hsa”
• Click on the blue “Jump to hsa” link and enter your information
