You shouldn’t be editing that file. Your changes will be lost on update, plus it is never wise to edit the core code.
See this guide on adding custom checkout fields: https://docs.woocommerce.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/
If you can’t quite figure out the code you need for this or how to do it, then you may need to hire a developer or use an extension like Checkout Field Editor.

I am trying to figure out how to export a customer note/”comment”. I have done it before but it’s been several months and I can’t figure out why it isn’t working now.
In the woocommerce/includes/class-wc-checkout.php, I added the following.
However, this information is not appearing in the individual orders or in the exports.
woocommerce_form_field( ‘my_field_for class’, array(
‘type’ => ‘text’,
‘class’ => array(‘my-field-class form-row-wide’),
‘label’ => __(‘Who is eating lunch? Please provide student(s) name & classroom(s)’),
‘placeholder’ => __(‘e.g. Sally/1st, Michael/KH, Parent’),
), $checkout->get_value( ‘my_field_name’ ));
echo ‘</div>’;
