Newb starter question

Hi,
Really excited to get going but totally frustrated. Started going thru the onboard tutorials and not finding on my screen what the tutorial is asking for. Am using latest version. Example, the landscape painting tutorial. When it says to click on the plus symbol to the right of the eyeglass in order to add a paintable layer, it doesnt exist. Followed each step and it just doesnt exist?
Thx
