That basically looks right.
- Form 1040 is the main tax return form.
- Schedule C-EZ has the revenue, expenses, and net profit from your business. Since your expenses were less than $5000, you can use C-EZ instead of the full Schedule C (assuming you also meet all the other C-EZ requirements).
- Schedule 1 is used to include the net profit from C-EZ into Form 1040.
- Schedule SE is for the self-employment tax. Section A is the "short schedule" and Section B is the "long schedule." You need to look at the flowchart at the beginning of SE to determine which one you need to complete.
- Schedule 4 brings the self-employment tax from SE into Form 1040.
Of course, depending on your personal tax situation, there may be other forms you will also need to include with your tax return.
