you don't need and shouldn't prune at this stage. earlier pruning can help if done right, but many people, including on here, don;t have a clue how to prune right.
for instance, ignore anyone who says to prune fan leaves to expose the bud sites. most of the light is absorbed by the leaves, cutting them hurts the plant.
pruning earlier in the plants life can help you shape the plant to fit the space you have available.
