Yes you have to enter all the 1099. Was it from personal broker accounts or from tax deferred retirement accounts like a 401K or IRA?
For personal accounts you should get a 1099B, 1099Int, and 1099Div. Maybe it will be on a consolidated 1099 statement. You have to enter all the 1099s. If you get a consolidated statement. That will have sections for 1099-Int and 1099-Div and 1099B. You need to enter each section in the right place. So read it carefully and look for headings.... 1099-INT for interest or 1099-DIV for Dividends or 1099B for sales.
For 401K, IRA or retirement accounts you will get a 1099R.
You may may be able to import all the forms. How to import your 1099
