IN Turbo Tax, where is the the page you add the amount of money you contributed to your spouses HSA?

If you made a contribution to your spouse's HSA (so not through paycheck withholding) you can add that separately.

Here's how:

• Click on Federal Taxes,  Deduction & Credits
• Choose "add/edit" HSA, MSA Contributions
• You will see a page titled "Your HSA Summary" which will show any deductions already computed from your W-2  
• Choose Edit, Check the box for HSA, Continue
• You'll now see a screen that says "Here's what we have so far"
• Choose done and continue until you get to a screen that says "Let's enter your HSA contributions"
• In the box "Any contributions you personally made (not through your employer)" enter the amounts you directly contributed outside of paycheck withholding
