Q:

apksigner returns back with nothing

as you can see from the title I am having difficulty getting apksigner to work. I have tried using the terminal in android studio and the command line however they both seem to return exactly the same; with nothing.
No matter what I type in I end up with the same result.

A:

You could try this:
//Go to the location of `apksigner.bat` file    
C:\Users\Administrator>cd C:\Users\Administrator\AppData\Local\Android\Sdk\build-tools\28.0.3\

C:\Users\Administrator\AppData\Local\Android\Sdk\build-tools\28.0.3>apksigner --help

the apksigner.bat file may be in another folder which is different from the example.
