Payment plan Voucher

Since I'm using an Auto Debit System for paying the IRS I know I have to mail in Form 1040-V. but since I have an Auto Debit system set up will my first payment come out of that or do I need to mail a check with my first payment listed?  Also do I mail Form 9465 along with 1040-V, to show acct and routing numbers?

If you requested an installment agreement with the IRS on Form 9465, and indicated that you’ll make an initial payment with your return, this initial amount must be paid by check with the 1040-V voucher.  This is true even if you requested direct debit of future payments.  The IRS takes 30 days (longer after March 31st) to process the installment agreement request and begin the direct debit payments.
