Keep in mind, that Photoshop is a learning curve ... and it is difficult to learn.
And Help makes sense only after somebody else tells you how to do what you need help with.
And the Adobe site offers tutorials ... which are merely ads about their products.
I tried Lightroom free-trial from the adobe webpage.
Lightroom was not for me, maybe because I do more editing.
But it seemed easy to use, and may be perfect for your needs.How-to-learn Photoshop
There are lots of sign-up-for-the-course offers on the web ... and these are very helpful
There are Photoshop tutorials on Utube.
Also you can web search exact how-to questions: For example How to copy-and-paste-in-Photoshop-Elements.A free alternative
Now, if you do not want to spend money for a photo editor, download free Gimpshop.
I also use Gimpshop.
The Gimp is free, and it is also a powerful photo editor.
You can web search How-tos with Gimp also.
And the nice thing about web searching Gimp how-tos vs web searching Photoshop how-tos is there are a lot fewer promotional come-ons with Gimp [and more up-front help]
