Thanks for getting back here, jay87.

I'll share some steps where you can get the ACH form.

If you have QuickBooks Payments enabled and want to charge a customer repeatedly on a fixed schedule, you can download the authorization form by going to the recurring transaction page in the Merchant Services page. 

Here are the steps:

1. Sign in to your Merchant Services account.

2. Under the Recurring Payments sections, select the Create recurring payment link.

3. In the Set Up Recurring Payment page, scroll down to the Payment Method section and click the Signed authorization link. The form will open on a new tab.

4. Download or print the authorization form and send it to your customer.

I've got this sample screenshot for a visual reference:
