1099 B

First time I see 1099 B on Federal tax form.    All of the info was uploaded unto the site however there is this field that I just dont know what to enter.

Tittle 

How did you receive this investment?

Now, I dont do any of the trades myself.  The bank brokers do everything for me so I am not sure what am I to do.  Safe to assume I need to enter I purchased it considering I never made trades myself.  Just want to make the right entries.  Someone help.  I dont know what I need to enter since this isnt found/reported on the 1099 B form
