Why is TurboTax saying that my refund will be higher itemizing my deductions when standard deduction is greater than my itemized deductions?

Please check what's [posted to your tax return.

You can preview your tax return by going to:

1. On the menu bar on the left that shows.
2. Select Tax Tools
3. On the drop-down select Tools
   1. Tip: If you don't see the dropdown for Tools,
   2. Minimize the federal and state options using the down arrow.
4. On the popup menu
5. Select View Tax Summary
6. On the left sidebar
7. Select Preview my 1040.
   1. Verify your filling status as Married Filling Jointly
   2. Also, confirm what is posted to box 12 (Deduction)

You will have to pay your TurboTax fees to see the other forms.

I suggest you look at schedule A
