Hi Andra,

If you like direct changes in the code for site title then goto theme folder -> library-> structure-> header-extension.php on line no184 to 192 remove previous code and add this below code

<div id="site-logo" class="clearfix">
          <?php if(is_home() || is_archive() || is_search() || is_page_template( 'page-template-corporate.php' ) || is_page_template( 'page-template-gallery-four-column.php' ) || is_page_template( 'page-template-gallery-three-column.php' ) || is_page_template( 'page-template-gallery-two-column.php' ) || is_page_template( 'page-template-blog-image-large.php' ) || is_page_template( 'page-template-blog-image-medium.php' ) || is_page_template( 'page-template-blog-full-content.php' ) ){?>
				<h1 id="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?> <sup> TM</sup></a></h1>
				<h2 id="site-description"><?php bloginfo( 'description' ); ?></h2>
                <?php } else { ?>
				<h3 id="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?> <sup> TM</sup></a></h3>
				<h4 id="site-description"><?php bloginfo( 'description' ); ?></h4>
				<?php } ?>
			</div><!-- #site-logo -->

Note: If you made direct changes in the code then while updating to new version all your customized code will be lost. So better make a child theme and add the above code. If you are unable to do it then make direct changes in the code and each and everry time you update to new theme then same customization you have to do.

After that add below code inside dashbaord -> appearance-> customize -> design options -> custom css

sup {
    font-size: 16px;
    bottom:23px;
}

Thank you!
