However, I just don't know which items are the ones that are not uploading.

Do you have any files with a different file format, that is not supported for iCloud? Perhaps special graphics formats? Also check your videos.
Compare your Photos Library on your Mac with the Photos Library on the iCloud Webpage at www.icloud.com.
At www.icloud.com you will see all photos and videos that managed to upload.
Perhaps you can spot one missing file.
