If you didn't make any election to be treated as an S-corp or C-corp for the year, you'll file the same as in the past except you will enter your EIN in the section for your self-employed income so that it will print on your Schedule C. For tax purposes, without elections for different treatment, you remain a "disregarded entity".
You will take deductions for the payroll expenses this year, which is likely new for you so feel free to come and ask questions as needed when you get to that part of the data entry.
Congratulations on your growth and success!
