You don't report a salary for your Single Owner LLC. Instead, your LLC defaults to be taxed as self-employed and the net income from your business (business income minus all business expenses) flows to your main tax form for income taxes and self-employment taxes if your net income is greater than $400.
I believe your first question is asking about money you contributed to the business, since you said you didn't have income but you do have a profit. This should be tracked for your LLC accounting records and you'll read the value on your business balance sheet. You don't report this for taxes. Self-employed taxes are the easiest type of business, because all you report is income and expenses on a schedule C with your personal tax form.
Trying to deduct a salary you paid yourself; would get you in trouble with the IRS (as a self-employed business), so it sounds like you're in good shape.
