I started an S corporation but at present, I am the only shareholder. I also worked and receive a W2. How do I file? should i file the S. Corporation first then my 1040?

I worked for another company and received a W2. separate and apart from The S Corporation that I have formed. I also have a few clients that the corporation generates income from as well as expenses.  How do I file the Taxes?  Should I file the S Corporation return first seeing that I am the only shareholder so far and a 1040 individual return as well?
