Great question @maryann-campos, and welcome to the Brainery!

There are a couple of different ways to create a Legend.

1. select all the markups on the drawing, right-click, and select Legend > Create New Legend. This will create a legend of only the material you selected. You don’t have to select all of them, just one and it will report the other instances of the same tool.
2. Once you have all you tools organized in Toolset, click the Properties Gear to the right of the Toolset header. Go down to Legend > Create New Legend. I like to do it this way, because it will create a legend of everything in that Toolset, but only the ones you use.

Hope this helps! Thanks for asking, so future answer seekers can search and find what they need.
