Lengthening an audio clip

I cut a piece of audio a little too short. I’d like to lengthen it out about a second at the beginning. Is there a way to do this without going back to the source audio? I looked everywhere for an answer but couldn’t find one anywhere. Thanks for you help.

If the Audacity project is still open you can “Undo” previous actions - Select “Undo” from the Edit menu or use the keyboard shortcut Ctrl+Z
