If you're looking to change your Twitter handle, here are the steps:
Login to your account on your desktop or through the Twitter app.
Click on 'Profile' in the sidebar (on desktop) or tap on the hamburger icon (☰) and select 'Profile' (on mobile).
Click on 'Edit Profile' or the Edit button (✎).
Locate the 'Username' section (or 'Account name' for some regions).
