Many warnings from Duplicator scan of my Live site at Flywheel

Yikes! I haven’t used Duplicator in quite some time so I don’t know if I am completely missing something in setup or what. I get errors for:

Web server: Flywheel/4.1.0 (not supported?)
PHP Setup: Max Execution Time: ‘120’ (min recommended: 150)
Total Size: 1.46GB (I must be doing this wrong!!!)
Large Files: Okay, I can exclude these and copy them manually.

Do I understand correctly that I should include the entire WP install from / ? I don’t see why that’s necessary. Shouldn’t wp-content and the db be enough?

Thx,
Jeff
