Thank you so much for this information.
But the issue is that Treasury Direct doesn't issue a regular 1099INT with individual box level split up.
All it shows is the total interest paid for the year with a note (Ref. Box 3).
So could you please confirm if I should enter that amount only in box 3, or in both box 1 and box 3.
Of course, I see that my tax liability goes up much more if I enter in both !
