No....box 12 on a 1099-DIV is only for Municipal Bonds .....and those $$ can come from state/county/city bonds issued in states other than your own (except if you own a mutual Bond Fund that happens to be state-specific).
For US Govt Bond interest from a Mutual Fund (like VUSXX)
1) In TTX, when US Govt bond interest is reported from a Mutual fund on a 1099-DIV form, those $$ are included in box 1a, along with other types of dividends from Funds, or even stocks, that you may own at that brokerage. In order to break out the $$ that came from just the US Govt bonds (to be state tax-exempt), there is a page AFTER the main form entry, with a bunch of checkboxes.....the top one you must check "A portion of these dividends is U.S. Government interest" Then on the next page, you enter the sub-amount that came from US Govt bonds. BUT you need to calculate that sub-amount yourself from the data that the fund gives you at the end of the year (usually in late Jan to late Feb).

As a separate issue:
2) IF, instead, you also own actual individual US Govt Bonds in your Brokerage account...then those interest $$ are reported in box 3 of a 1099-INT form....and just filling out that 1099-INT with the $$ properly showing in box 3, they will automatically be handled as being state-tax-exempt.
