First, welcome to the forum!
Second, there is no such thing as a dumb question... now the odd answer, no guarantees there... lol
The answer to your question basically depends on several factors. Assuming you are playing using sheet music made for accordion, sometimes there is only one line which is the melody or right hand. The chords are usually placed in the notation and written as Cm, C7th, etc... and other times there are lines dedicated for the right and left hand independently, and the majority of the time, this is how accordion music is written and is the suggested way to play the music.
Here is an example of a piece of sheet music for accordion that is only of the right hand, and to make this more interesting, doesnt even offer much assistance for the left hand (but with practice and experience, this becomes less of an issue, I promise).

An example of accordion music with separate left and right hand staffs:

When there is only one staff dedicated to the right hand, you play the bass/chords as suggested in the text. When there is a separate staff for each hand, one has a higher level of detail and information as to what and how to play on the left hand.
Thats basically the readers digest version and of course the third option is that later on, once you develop greater levels of skill, you can even add/remove or change whatever the music notation tells you to play on the left hand and do your own thing, should you wish.
I hope that kind of answers your question?
