Get your taxes done using TurboTax

I'm in CA and have Vanguard funds. I manually enter mine so I don't know if the import picks up all the right amounts for US Govt Obligations. I have to make a spreadsheet to calculate the amounts each year.

Vanguard used to include the extra sheets with the 1099 statement but now you have to get them online to see which funds you can exclude and how much. I go though and circle all my funds.

Here's the sheet I make every year for my Vanguard in California.  You have to get the Dividend for each fund by looking at the detail page from the Consolidated 1099.  Don't know what funds you can include for MA.  Not all mine have 50% assets in California.  You have to read the little footnotes in the US government pdf.
