If the contributions to your wife's HSA were made through payroll deductions and they were reported on her W-2 in box 12 with code W, then they should be reported on Form 8889 line 9. These contributions are not tax deductible because they were made with pre-tax funds.
Form 8889 line 2 represents any contributions that were made directly to the HSA using after-tax funds of your own. That amount would be deducted on the tax return.
When you go through the Deductions and Credits > Medical > 1099-SA, HSA, MSA section of your return, be sure that you indicate that only your wife has the HSA account. Then all questions will be related to your wife's HSA, not yours since you stated you do not have an HSA.
