High Sierra iTunes can't see iPhone

[Pogopedia]

Grrrr...
iMac/iPhone 8 — Both OS' are latest, have swapped out several USB cables, used different USB ports, rebooted both several times.
I understand the next move is to un/reinstall iTunes.
Can anyone confirm this as a successful strategy?
I have played 52- Pick Up before.
Who has the most current/thorough checklist for this process?
Thanks, everyone!

PROBLEM SOLVED. Simply install new copy of iTunes over the corrupt one. No trashing, uninstalling, etc. Don't even open the hood.

I have the same problem with my Fiance's SE. iTunes sees my X but not the SE as of yesterday. Worked fine on Sunday evening.
Weird thing is, is that the Photos App sees the SE on my MacBook.

Get a cable that is made by apple...not a knockoff.

This worked on my mid 2012 MBP running High Sierra and my iPhone 6S when I updated to iOS14. Thanks.
