Is it possible to find my amended return on the turbotax website?

If you amended your return through TurboTax, it'll be available with the rest of your forms. If you amended outside of TurboTax, you won't be able to see it.

under what tab do I find that? Its not under "download forms" when I download forms it just gives me the original forms I filed not the amended ones.

Try this:
