Welcome to the forum.
Unfortunately, you have posted to the Premiere Elements forum. PrElements is the video-editing half of the Photoshop Elements/Premiere Elements bundle. You want to post to the Photoshop Elements Forum.
PS - I could tell you how to do that in Photoshop, but Photoshop Elements has some slightly different Tools, than does its "big-brother," and I would probably muddy the waters. The people at the PSElements Forum will be able to quickly direct you how to do it best, in that program. Also, when you do post there, please attach an Image, or what you are working with, to help others see your situation, and can better help you. If you need details on Attaching and Image, see this ARTICLE.
If you have two images of the scene you could try Scene Cleaner with the Guided Edit Photomerge. If not then use the Healing brush. Set it to Content Aware in the option bar.
