In the project settings, change "Timeline resolution" to Custom and type in your dimensions in the "For X * Y Processing" fields. In the deliver tab, the Resolution should already say "Custom" and have the numbers typed in. Just select your codec details, add to render queue, press "start render" and you should be good.
*edit* If your source footage isn't the same aspect ratio as your custom settings, be sure you tell DaVinci how to handle it in the "Image Scaling" section of the project preferences, or you could end up with pillarboxing, letterboxing, cropping, scaling, or stretching when you don't intend to.
