State tax filing

"....I sold my skills as an individual amateur and people paid through check. "

That was self-employment income.    You do not need to try to spin it as anything other than self-employment income.   You do not have to have a "name" for the business or an LLC----what you were doing was self-employment----as far as the IRS is concerned, you had a business.  You are subject to self-employment tax for Social Security and Medicare, and ordinary income tax.

Instead of asking us to do all of your calculations for you----enter the information correctly and completely into the software and see how it comes out.

If you have self-employment income for which you will pay self-employment tax for Social Security and Medicare,  you will need to use online Premium software or any version of the desktop software download so that you can prepare a Schedule C for your business expenses.
