I posted an answer earlier today and wanted to review it again, because I had another idea. However it is not in my list of answers. Can it be that the question was closed/deleted because of it’s poor wording? How could I still locate it?
Go to the list of answers in your profile. At the bottom, there's a link 'recently deleted answers':
That will lead you to a page which "shows answers you posted that were deleted in the last 60 days. This includes answers to questions that were deleted."
Normally, you'll need 10k reputation to see deleted posts, but an exception is made for your own posts and for deleted questions you wrote an answer to.
