Get your taxes done using TurboTax

In the Federal section, enter your 1099-Div.

1. On the screen Let's get the details from your 1099-DIV or brokerage statement, check the box My form has info in more than just these boxes (this is uncommon). A drop-down will appear, and you can enter the amount of tax-exempt dividends in box 11.
2. Continue to the screen Which state are your exempt interest-dividends from? If the entire amount isn't from MA, you can check the box I earned tax-exempt dividends in more than one state. 
3. A drop-down will appear and you can add the details.
