Thanks. This information was included with my 1099 packet from Vanguard, so that was convenient. I had VUSXX fund, which only has the US treasury at 80%. And then the California Municipal Fund is 100% California, so in that case I don't think I have to worry about other states. I tested the import (the direct import from Vanguard), but TurboTax is not able to calculate the portion that is exempt/etc on its own as of this time.
