How do I add a required field to the checkout page, such as a checkbox, so I can't checkout without it?

Answer 1

If we are talking about the base component "sale.order.ajax" or "sale.order", then you can open:

YOUR_DOMAIN_NAME.COM/bitrix/admin/sale_order_props.php?lang=ru

Select the type of face, and set its property in this way.
