I know that 1099-Div information can be imported into TurboTax from financial institutions. Is there an equivalent way to get capital gains information?
You can import most 1099 info. Capital Gains are on 1099 Div and 1099 B and maybe 1099 Int. What are your Capital Gains from? If you have sales you enter the Sales price and cost and then Turbo Tax calculates the Gain or Loss.
