All I see is the google street map view, is that what you are talking about? As far as Trulia goes it pulls a lot of their information from public sources and is not accurate on a lot of properties. I am a real estate agent and do not work for Trulia. But the inaccuracy of Trulia can be a problem in general not so much that it will effect the value of your home just because it creates confusion.
At the end of the day your home is worth what it is worth and Trulia will not effect it. Try not to drive yourself crazy.
I really do not have a ton of advice for you to correct it. You would have to deal with Trulia and Google and I am not sure that you can even get in touch with someone at either company.
