There's TWO places on Delta's website that you need to update. One is the profile page that rnlevi mentions, and the other is for each PNR. Go into your reservations and look for a link in 3-point font that says something about TSA or secure flight.
Update both sections, and make sure that they match your ID as well as each other. For example, I discovered that my profile said that my name was the correct "ThrowDownYourLeavyScreens", but the TSA data listed on the PNR page said that my name was the quite incorrect "ThrowUpYourLeavyScones".
