When entering interest on TurboTax, there is a checkbox right below that section that you must choose in order for the Box 3 to be displayed. That is where interest from US treasury issues are entered, and will display in a different column. It's all right there and easy once you see it, but it is all too easy to zip through entering simple amounts like interest. This tripped me up the first time around, but when I located Box 3, the Virginia tax return was correct.
