Is this legit or Bogus offer to install Photoshop Elements 2020?

[#1]

I recently ask a question on this forum and someone replied and said I could contact Adobe support directly and gave me the email address. 

Adobe Systems Incorporated <adobe.community@yahoo.com>

I reached out to them and they said I need to update from Photoshop Elements 14 to PSE 2020. I am willing to do this and the latest email from them is as follows:

They sent a legit looking receipt for $79.99. with an Adobe Systems Inc office address of 29322 Network Place, Chicago, Il.

Should I do this or download directly from Adobe site? What I was looking for was help installing and they are offering that but I want to make sure it is legit.

Thanks for your help!

This is a scam. Adobe would never use a Yahoo address.

Thanks! Yes, I checked further and found it to be a scam. Stupidly, I had already downloaded the pdf invoice they sent. Fortunately I had just created a restore point on my computer just prior to the download so I restored.
