Hello @susans98593130 I'll try to help you. You'll know that when you add content from Adobe Stock into a project and you select that image or element on the canvas there is a panel on the left hand side full of options.
For images/video: click the i icon and the little info panel pops up. I often manage to highlight this with my mouse and use Ctrl+C then Ctrl+V to paste into a note somewhere if I need to keep the information.

For audio: click the audio track in the timeline, then click the 3 cots in the panel to open Source info.

Click Source info and you'll get an info pop up like this with the audio track details.

You can then paste this info wherever appropriate e.g. a YouTube description if needed. I hope that helps!
