We have this guide to help you out with Plagiarism and How to Avoid It.
As for a website where you can upload a paper and then have it checked for plagiarism, I found Grammarly, which checks grammar and plagiarism mistakes. You can copy and paste your paper into their text box to see their answers. To test it, I put a paragraph from an article in it and it definitely knew it was not original material.
You may want to contact the Academic Support Center as well if this is a concern for you.
