Tune cornering — acceleration and jerk, only if ringing persists
Deliberately last. Ringing is a mechanical fault the great majority of the time, and lowering acceleration merely hides a loose belt at the cost of every print you make afterward.

How to do it
CHECK THE PRINTER ITSELF FIRST. Many machines run this in firmware rather than the slicer — FlashForge calls it Vibration Compensation, Klipper and Prusa call it Input Shaping, Bambu runs it as part of its own calibration. If yours has it, run that and you may be finished here.
In the slicer, look for CORNERING under Calibration. Recent OrcaSlicer and FlashStudio renamed it from "ringing tower", and offer a second version that also measures input shaping frequency and VFA.
Go back and re-verify belt tension and wheel preload first. Seriously.
Only if the frame is sound, print the cornering or ringing tower.
Lower acceleration until the echo disappears.
Accept the slower print. If the cost feels too high, the fix is mechanical, not this setting.
How to read the result
Ghosting echoes after corners are gone.
Your slicer may do this for you
Current OrcaSlicer and FlashStudio file this under Calibration as CORNERING, usually with two entries — one for cornering alone, one that also covers input shaping frequency and VFA. Older versions, and PrusaSlicer, call the same thing a ringing tower.
