Text widget sidebar appearing at bottom of page, not top

New to wordpress/web site building.

Under “Appearance”, I created a TEXT sidebar, calling it “Header” and wish to put this text with hyperlink onto my homepage under pull down menus, above the purple “Get Everfest” banner.

But I get lost when I go to the homepage – do I plug this in via the GDLR shortcode or do I use the page builder section? Either way, I’m not sure how to get that sidebar. Any GDLR shortcode puts it at the very bottom of the homepage, and there’s no seeming way to edit it to appear at the top.

HELP! ??
