OK a couple things, a LLC (single member) is reported on your return as part of your 1040. Many form this because of liability reasons and it is less complicated than a regular corporate return.
A Corp return (non LLC) has a separate 1120 to report income and expenses.
Both of these need to set up with your respective State ahead of time.
So you have right now a sole proprietorship, which is reported on Sch C business as part of your tax return.
Now to first question: You don't need to pay yourself a salary and net profit (business income less business expenses) from the business is your income. You will pay income tax and self-employment taxes on this net profit.
Don't worry as TurboTax does this for you.
