What is an allele? is it an actual physical object or is it just like saying it's an alternative form of a gene? I don't understand. Can someone please explain what an allele is? I've looked all over the internet.

It is as you suggest an alternative form.
If I had to explain it using my own words it would be the following:
An allele is a specific version of a DNA sequence, which is found at a particular location in a chromosome

Does it somehow answer you question or still confused?

Oh, ok, so basically there is the gene, which is the expected trait, and then, hidden along, is the allele, which is a small possibility of a different trait?
