The last time I backed up my iPhone 8 to my PC I somehow managed to create an album on my phone that I have no power to delete. I understand that I probably manually downloaded the album from my PC. Not sure how I managed it but HOW DO I GET RID OF THAT ALBUM? it is a block of 899 photos.

It sounds like the photos synced to the phone via iTunes. To delete, sync again as described in the following from Keep your photos safely stored and up to date on all of your devices - Apple Support
If you don't want the synced photos
on your iPhone, iPad, or iPod touch anymore, turn off syncing in iTunes
and they'll be removed from your device. You can turn off syncing for
some of your photo albums or all of them at once.
Stop syncing some albums
Stop syncing all photos
