Should be in the Federal area where you make the selection....as long as they were actual US Treasury Bonds/Notes or US Savings bonds.
For individual bonds you hold, the entry for that interest is in box 3 of a 1099-INT form. And the software knows what to automatically do with it from there-on for the state.
_____________________________
For US bonds interest held in Mutual Fund Bond accounts, that are collections of bonds, those $$ show up in box 1a of a 1099-DIV. For those, if you want to subtract the US Treasury interest from state taxation, you need calculate the sub-portion of the box 1a $$, that came from US Treasury obligations yoru self...using whatever data the financial provider/brokerage supplies separately as to what % came from US treasuries. If you have multiple funds that fed $$ into the box 1a value, you need to calculate them separately, and total them together.
Then on the page after the main form, there is a selection box you need to select, indicating that a Portion of the $$ on the 1099-DIV from came from US Government interest......then a page or tow later you enter that amount, and that $$ amount will automatically be subtracted from State taxable income on the state forms.
