Can anyone help me undersand what I need to file my taxes using Turbo tax. I use IB as my broker and I am confused with what forms I need. So far I added my 8949 to Turbo Tax. Do I need something from the 1099-B as I see it when I log into Account Management? Also, my gains are different on my 1099-B, 8949, and when I run PortfolioAnalyst to look at my entire year PnL. Any guidance would be much appreciated.
