I did respond to this question that you posted under general area but thought that I would paste my answer here as well.
Trulia does not accept for-sale-by-owner listings so that is probably the problem with your inputting your home on the site. You would need to be working with a real estate agent and be listed on the MLS in order for your property to be seen as "for sale" on this site. Trulia states that this is a means for them to cut down on "scammers" on the site.
However; you can post your home for sale on zillow.com or craigslist.com for free.

Our service is free, and there is no charge to have listings posted on Trulia. At this time we do not add For Sale By Owner listings. We are aware that many individuals who have FSBO listings would like to have their listings featured on Trulia.
