There are not additional forms that need to be included, but there are specific addresses.  Please see below.

The instructions for filing 9465 directly in this IRS document: https://www.irs.gov/pub/irs-pdf/i9465.pdf - 

"If you have already filed your return or you’re filing this form in response to a notice, file Form 9465 by itself with the Internal Revenue Service Center using the address in the table below that applies to you."
