What I use to show jetpack sharing options above and below posts on Genesis themes.

functions.php

remove_filter( 'the_content', 'sharing_display', 19 );
remove_filter( 'the_excerpt', 'sharing_display', 19 );

add_filter( 'the_content', 'share_buttons_above_post', 19 );
add_filter( 'the_excerpt', 'share_buttons_above_post', 19 );

function share_buttons_above_post( $content = '' ) {
	if ( function_exists( 'sharing_display' ) ) {
		return sharing_display() . $content;
	}
	else {
		return $content;
	}
}
