We had done everything you suggested. We examined the difference between TurboTax's total for the amount of dividends that represent "interest from U.S. Obligations" and the amount we got when we manually added up the individual amounts. It looks like the first fund that had interest from U.S. obligations (as listed in the Federal form) has been omitted in TurboTax's calculations. The amount of this fund's dividend that "represents interest from U.S. Obligations" and the difference between the total we get and the total TurboTax gets is the same.
