You must enter the gain or loss on sales of securities, dividends and interest earned, etc. regardless of whether you withdrew money from your account or not.  TDA will provide you with a form known as a Consolidated 1099-B which includes all the information you need.  Many of these are now available (I got mine online yesterday).  And in the TDA Tax Center on your account screen they give instructions on how you can have the information in this report automatically downloaded into TT online.  I did it yesterday into my TT Download version and it worked perfectly!
