Brush tool problem
Hello out there: I'm having an issue with Photoshop CC, version 19.0 and I have no idea how to contact Adobe for help. I'm 77-years-old and I don't even know what a forum is but it looked like a place to maybe find an answer. Following is the information about my computer - 

As you can see, I have no idea what I'm doing. The issue that I want to ask about is rotating circles of dots when I'm using the 'Brush Tool' or trying to clone. Below is a screen grab showing both circumstances. Cloning is especially troubling since mostly I can't see where the brush is. I would be grateful for information about how to solve this problem.
