Be sure that the US Treasury Interest in entered in box 3, at the 1099-INT screen. When you first see that screen, check the box "my 1099-Int has more than just a box 1", to get access to box 3.
Treasury interest must be entered in box 3 at the 1099-INT screen. When it is entered there, TT will automatically make the deduction on the state return. There is no other way to make the adjustment.
After entering your 1099-DIV, you will encounter a screen "Tell us if any of these uncommon situations apply to you". Check the box "A portion of theses dividends is U.S. government interest". Enter the amount provided by Jones. If they only provided a percentage, you will have to do the calculation. Enter an amount, not a percentage.
