The 1099-INT showing interest on Treasury Obligations notes that the interest is referenced to Box 3. The Turbo Tax interest input area only has an input for Box 1.

There is a small box on the page which you have to click on. My form has information in more than one box. Once you click on it, the page will open up to desired box you are looking for, namely; Box 3 - Savings bonds and treasury int.

There is a little checkbox below it that says My form has info in more than just box 1.  Click that and it will open up.
