To extract the left channel of an existing stereo Sound as a new mono Sound, select that stereo Sound in the list and choose Extract one channel... from the Convert menu, Then set the Channel to 1 and click OK. A new mono Sound will appear in the list. For the right channel, set Channel to 2.
The name of the new mono Sound will be based on the name of the original stereo Sound. For instance, if the original Sound is called hello and you extract channel 2, the new Sound will be called hello_ch2.
This command also works if you select more than one stereo Sound. For each of them, Praat creates a new mono Sound.
