@santhida
remarks field is already available in POS
if you want to set value to that field do this changes in
pos_payment.js
add this line

this.discount_field = frappe.ui.form.make_control({
			df: {
				label: __('Remarks'),
				fieldtype: 'Small Text',
				placeholder:__('Enter Remarks.'),
			},
			parent: this.$invoice_fields_section.find('.invoice-fields'),
			render_input: true,
		});
		this.discount_field.toggle_label(true);

if you dont want to show Lable do

this.discount_field.toggle_label(false);

and
add this line in bind_events

this.$component.on('click', '.submit-order-btn', () => {
			const frm = this.events.get_frm();
			const doc = this.events.get_frm().doc;
			const paid_amount = doc.paid_amount;
			const items = doc.items;
			const out_stand = doc.outstanding_amount
			if (paid_amount == 0 || !items.length) {
				const message = items.length ? __("You cannot submit the order without payment.") : __("You cannot submit empty order.");
				frappe.show_alert({ message, indicator: "orange" });
				frappe.utils.play_sound("error");
				return;
			}
			if (out_stand > 0){
				const message = __("You cannot submit the order with  Outstanding payment.")
				frappe.show_alert({ message, indicator: "red" });
				frappe.utils.play_sound("error");
				return;
			}
			let remarks = this.discount_field.get_value()
			frm.set_value('remarks', remarks)
			this.events.submit_invoice();
		});

Output

@santhida You can use “Customize Form” to do it.
Please refer to documentation.
