How to change PayPal account on form?

Also- I just made a new form and it's saying it's connected to an invalid
PayPal account.
When I try to change it- I don't have any options- what's going on there?

The PayPal field is already added to you form, so you will need to specify your PayPal account address. Click on the payment field, then click on the magic wand icon and add your PayPal account.
