Align sidebard to the right

details to the formatting will depend on your currently used theme.

ideally, please post a live link to your site to illustrate your problem, and to allow somebody to investige the formatting, using a browser inspection tool.

This is a relatively easy fix. If you’re not already using a child theme to make modifications to your theme I would suggest you implement one before proceeding with my suggestions.

Child themes are relatively easy to set up, you can read all about them here: https://codex.wordpress.org/Child_Themes

If you’re still struggling you can also try the One-Click Child Theme plugin https://wordpress.org/plugins/one-click-child-theme/

As for the CSS itself, you could add the following CSS to your child theme for the desired effect.

#sidebar {
	text-align: right;
}

#sidebar #mc_embed_signup_scroll {
	overflow: hidden;
}

#sidebar #mc_embed_signup form {
	float: right;
}

#sidebar #mc_embed_signup input.button {
	float: right;
}
