I am customizing Airy New. I did not provide input under (Your Payment details) but the final invoice print show a line (transfer amount to the business account below)

Hi there, mezawi.

Thanks for sharing a screenshot of your customized sales form. The information that you can see in the Your payment details section is just a sample banking information. It will not show up in the actual invoice that you'll be sending to your customers unless you will put in your own banking details. 

Here's an article about this feature for more details: Customise Invoices, Estimates, and Sales Receipts in QuickBooks Online. 

Let me also share these additional articles for more reference in case you're interested in using these features:
