I looked at all the previous questions and answers on this topic (on Upwork Community), and here is my summary:
-- Pre-2015 = Find trash can at either each saved search or at the top at My Search Feed. This is no longer available.
--2015-2018 = We're supposed to click on the three horizontal dots at the upper right and you're supposed to see saved feed or something similar, plus Atom and RSS. As of this writing, the 3 dot method is no longer available. There is only Atom and RSS and that's it!
2020 = Enter my Loom video on how to delete AND edit your saved searches! Finally! The answer to your prayers!
