Should be two ways of going about doing it that end in the same place on your end.
1.) Profile>Payment Settings> Preapproved payments.
Click on the profile, scroll down to the bottom and under the Payment Settings section, you should see Preapproved Payments in blue. Click on it and you're good to go.
2.) Wallet>Classic Site> My Money> Update next to Preapproved Payments
Click Wallet and in the bottom left you'll see Classic Site. Click on it and then select My Money on the left. You should see Preapproved Payments towards the bottom of the list. Click Update next to it.
Both of these paths should take you to the same area. Otherwise, you can call in and a customer service agent can change it for you, I believe.
