Checkout change order of fields porto theme

Hi,

I’ve installed your plugin and i’m having difficulties to adjust my checkout.
As i’m building a German store for the German Market, I need to comply with German law, so the checkout fields need to be in correct order..

see screenshot without your code (default display with empty middle colomn)

My Porto theme has a different checkout layout that conflicts with Germanized
I’ve read most support topics and found a solution that is almost good..

it add_action( 'after_setup_theme', 'my_child_adjist_checkout', 20 );
function my_child_adjist_checkout() {
   remove_action( 'woocommerce_checkout_order_review', 'woocommerce_order_review', 20 );
   remove_action( 'woocommerce_checkout_order_review', 'woocommerce_checkout_payment', 10 );
        add_action( 'woocommerce_checkout_order_review', 'woocommerce_order_review', 10 );
	add_action( 'woocommerce_checkout_order_review', 'woocommerce_checkout_payment', 20 );
} 

see screenshot of checkout with above code here https://ibb.co/fxhzZRm

1:i need a smal extra tweak to change the Zahlungsart Auswahlen mit bestellubersicht with the review, including the correct H3 headings,

2: How can i place the “inkl. MwSt, one row higer above the Gesamtsumme?

hope you can help me out , many thanks!

Best

A
