I want to push out a basic software package using SCCM

I need to push out SQL Management Studio 2016 to a few workstations using SCCM. I have access to System Center Configuration Manager on my desktop and as a test I was just going to use my desktop as what I think is called a distribution point. I started by going to the Software library and creating a package. I entered a name, manufacturer, etc. and for a Data Source, I just pointed to a folder on my local C drive that contains the .exe. I think that is set up correctly enough to work. Now I want to push to my desktop first as a test. I think the next step is to create a Device Collection, add my workstation to the Device Collection and then go back to my package and deploy to the Device Collection. I am a little concerned because when I to go create a new Device Collection is forces me to select a Limiting Collection. I am concerned I may accidently push to devices that do not need the software. Plus now that I have a Device Collection, how do I add my workstation to it? If I am going about this all wrong and there is a better way to push out and install an .exe file to specific workstations, I am open to all ideas
