How can I add another row to the total field in WooCoommerce cart, checkout and recipe mail?

Its too late but it can still help to others who are looking for the same :

Copy “plugins\woocommerce\templates\cart\cart-totals.php” to
“your-theme\woocommerce\templates\cart\cart-totals.php”

Open “your-theme\woocommerce\templates\cart\cart-totals.php” and add the following line inside the table tag

<?php do_action( 'woocommerce_cart_totals_custom_text' ); ?>

Then open your function.php and add the following:

add_action( 'woocommerce_cart_totals_custom_text', 'action_woocommerce_cart_totals_before_shipping', 10, 0 ); 

function action_woocommerce_cart_totals_before_shipping(  ) {
     echo "<tr class="cart-subtotal"><th>Title</th><td>Text</td></tr>";
}

Here is the result
