Answer: Once you have the brush created, then click on the Brush Preview that appears on the far left of the Options Bar at the top of your screen (must have a painting or retouching tool active in order to see it). That should cause a drop down palette to appear when you can click the New Brush icon (which is on the right and looks like a piece of paper with the corner folded down). After you do that you will be prompted for a name and your brush should appear at the bottom of the brush presets list that also appears in that palette.
