What types of broker income is included in the stocks, mutual funds, bonds and other figure? only capital gains?

[TomYoung]

All that is included in the dollar figure next to "Stocks, Mutual Funds, Bonds, Other" on the "Your 2018 Income Summary" page is the net gain or loss from your own trades.

It's not necessarily to total of your capital gains or loss from all sources.

In order to see that number you need to look at Schedule D.  That will indicate where your "net" gain or loss originates.

capital gain / loss; dividend income, interest income, returned capital, foreign taxes  on income allocated etc.  

Does not your Broker statement detail out all your investment income ?
