I would like to take my old account off my phone now

If you want to simply sign out of your Apple ID on your iPhone then open Settings ➔ Apple ID (Your Name at Top) ➔ Sign Out (At the bottom).

If you want to delete everything on your iPhone and reset it back to Factory Settings then open Settings ➔ General ➔ Reset ➔ Erase All Content & Settings. This option will erase everything on your iPhone and sign you out of iCloud and deactivate Find My.
