I don't know if this is helpful. I use AP My Business account to create and pay for my International shipping Customs Declaration forms. However because I find it easier I do not "Import from eBay" but fill in the form myself. The only information it has about me (pre-filled) is my name and my address (in case the parcel needs to be returned). The name and address come from my AP Account. Then I pay for the shipping cost,  print off the completed form, attach it to my parcel and take it to the PO where they just scan the barcode and give me a receipt for tracking confirmation. HOWEVER if you choose to import the order direct from eBay it is possible that your email address will be pre-filled - there is a space for it on the Customs form, also your phone number. You could I suppose simply delete that field - it is obviously not necessary, as it is blank on all my forms.
