Where is the return URL option in the Paypal sandbox?

Question

According to Paypal's documentation, one sets a return URL like so:

1. Log in to your PayPal account at https://www.paypal.com. The My Account Overview page appears.
2. Click the Profile subtab. The Profile Summary page appears.
3. Under the Selling Preferences column, click the Website Payment Preferences link. The Website Payment Preferences page appears

I am trying to test this in the sandbox, but when I go to the Profile Summary page, it looks like this:

There is no "Website Payment Preferences" that I can see.

Is this not possible in the sandbox? Or has it moved?

Useful but just change #1 to

1. Go to the sandbox( https://developer.paypal.com/ ) website and log in; click Test Accounts; select your test Seller/Business account; click "Enter Sandbox Test Site"

2. Click "Profile" at the top of the page.
3. Click "Instant Payment Notification Preferences" in the Selling Preferences column.
4. Click "Edit IPN Settings."
5. Enter the notification URL and select "Receive IPN messages."
6. Click "Save."
