Vanguard only gives you percentages for U.S. government obligations that are in their Federal Money Market Fund and their VTI ETF so you have to calculate the amount to be excluded from the state return. Turbo tax doesn't appear to be adding the amounts that are entered on the TT Federal 1099 form line 1a "U.S. government interest included in box 1a. I only have two 1099's with U.S. government interest and the amounts on Federal return don't equal what TT is populating line 4 on Virginia Sch ADJ/CG Subtractions (Virginia return is showing less).
