Importing passwords from Safari

Hello -

I’d really like to break my Safari habit, but had no idea how reliant I was on stored passwords / financial info!

Tried to import passwords from Safari per these instructions:

However, a critical step is unavailable. I can choose the browser from which to import bookmarks and settings, but the only item listed as available to import is “Favorites/Bookmarks.”

I’m running MacOS High Sierra 10.13.6, Brave 0.68.132, and Safari 12.1.2

Thanks!
