This may be a 10k+ user ability but give it a try...
- Go to your user profile for WPSE.
- Click on the "Activity" tab
- Below your reputation chart is a list of tabs, click "questions"
- At the veryyyy bottom left is a link "deleted recent question" - click it
If there doesn't work there's an "all actions" tab in the Activity profile which may shed some light. I could also link you to the question if need be.
As OP points out in the comments below you may also follow this link and replace {ID}
with your profiles user ID:
https://wordpress.stackexchange.com/users/recently-deleted-questions/{ID}
