2. Tap Edit, scroll down and tap “add field,” select a pronunciation name field, then type how to say your name.

If so, since adding the pronunciation, have you tried restarting your iPhone? If not, give that a try with the steps in this next resource here: Restart your iPhone - Apple Support
How to restart your iPhone X, 11, 12, or 13
1. Press and hold either volume button and the side button until the power-off slider appears.
