I have everything turned on, yet there is no photostream folder showing anywhere.
What have you turned on? Is iCloud Photo enabled, or my Photo Stream, or both?
You should not be trying to use my Photo Stream and iCloud Photos together. You will not be seeing my Photo Stream in Photos, if iCloud Photos is enabled. Then my Photo Stream will not be shown. The Photo Stream photos will appear in the "All Photos" album.
With a iPhone 12 I would not use my Photo Stream at all, as it cannot handle all of the media formats you will want to use on a modern iPhone. my Photo Stream does not transfer Live Photos or Videos.
Apple seems to be deprecating My Photo Stream. It is yesterday's snow. For several years we have been seeing this warning in the support documents: My Photo Stream - Apple Support
If you recently created your Apple ID, My Photo Stream might not be available. If My Photo Stream isn't available, use iCloud Photos to keep your photos and videos in iCloud.

How My Photo Stream works with iCloud Photos
My Photo Stream uploads your most recent photos (except Live Photos) so that you can view and import them to all of your devices. Photos are stored in My Photo Stream for 30 days. iCloud Photos uploads all of your photos and videos to iCloud and keeps them up to date across your devices.
If you turn on both My Photo Stream and iCloud Photos on an iPhone, iPad, or iPod touch, photos that you take with that device upload to both iCloud Photos and My Photo Stream.
If you use another device with the same Apple ID that has only My Photo Stream turned on, photos that you take on that device upload only to My Photo Stream. They don't appear on any devices that have only iCloud Photos enabled.
