making the sharing section of the dashboard accessible

I just created a WordPress site, and I am having an issue with the sharing buttons. I use VoiceOver on the Mac. So, I cannot drag the sharing buttons I want to include at the bottom of my posts into the correct location. In the widget area, I was able to locate a screen option button that let me turn on accessibility mode. I cannot find a screen option button to make the sharing section accessible. Am I missing something? If not, how can I add the sharing buttons to the end of my posts?

Thank you in advance for your assistance. I appreciate it.
