In the core parts bin near the bottom with the label connection the first icon (a single .1 connector) is what you want. If you drag that in to a view then Inspector (the lower right window) will let you change its attributes (number of pins, male / female etc.) to make most headers you could want. It will create the correct footprint in PCB view for the selected connector. The long pin version isn’t available but the gerneric version will work fine.
