I got a letter from the IRS about my direct debit installment agreement and I just want to be sure I don't have to mail anything back

No, if your request for an installment agreement via direct debit has been approved, then you don't need to mail anything else to the IRS.

In applying for the agreement, you had to supply information about your bank account. The IRS will handle everything from here until the debt is paid off.
