Welcome to the Community. I'd be more than happy to provide you with some additional details.
The residential address mentioned in the contractor's profile will be used to mail all 1099 forms by January 31. In case the contractor does not receive their 1099 form within 7 business days after January 31, they can print the recipient copies from within their account.
Please note that when you invite a contractor to enter their W9 information, they can create a QuickBooks Self-Employed account for free. This way, they can securely share their tax information with you and view the 1099 form after you've filed it.
