Where do I find the screenshots on my iMac?

Launch the Screenshot app and click on the Options button in the menu bar that appears and select the location where you want the screenshots to go.

You can see what's set currently so you can fine the recent ones.

You're welcome.

I learn something new here every day. Ain't it great?

Yup and thanks again.

Wow, I learned something new too. I wasn't even aware of the Screenshots app, I just used the old fashioned Shift + Command + 4 command had already changed where my screenshots were saved. This screensaver app is a time saver!
