move follow buttons to sidebar

Two questions:

1. Does anyone know how to get rid of the white strip above the header image? (Right now mine shows a search bar and social media icons.) I’d rather my header image be flush to the top.

2. Anyone know how to get the social media follow buttons into the sidebar? I clicked to enable this but they still show only above the header and in the footer.

The site is not live yet so I’m not sure how to show this…

Thank you!!
