Click on the Icons in the top bar and you will go to your profile which has a list of your questions

In the absence of any supplied information, the following assumes a default Ubuntu Gnome 18.04 desktop. In the title bar at the top right of the screen, left mouse click the section with your picture, reputation, and awards. This brings up your profile. At the top left, select "Activity", and from the list in the middle of the "Activity" screen, Select "Questions", third from the left. Your Questions on the starting (askubuntu) site will be listed.

Note that this answer, along with any other helpful answer or comment, is totally useless in helping the user find their (first) question, since some "helpful" administrator moved everything to another site (Meta, since the question was arguably not about Ubuntu, but how to use the site). Now the user's second question has disappeared!

Oh Meta-Meta where are you when we need you ;^O
