Welcome to Trulia Voices and thank you for your question. Since you've manually submitted your listing to us, you have the ability to edit it and specify that we don't display the address.
Access the link below to navigate to the My Listings section of your account and select the link to 'Edit listing details'. Then, select the option to edit the listing information. On the editing page, above the address field you'll find an option that says 'Don't publicly display listing address.' Check that option, save your changes, and our display will update within 24 to 36 hours at which time the address will be removed.
Please let us know if you have any difficulties with this process or if you have any further questions or concerns.
