When we say that a single-member LLC is a "disregarded entity," it means that you and the LLC are one and the same as far as income tax is concerned. The LLC is not something separate from you. The LLC's income is your income. You are not an employee of yourself, and you don't report payments from yourself to yourself. You just report the LLC's income as business income on Schedule C of your personal tax return. Your option 3 is the correct way to handle it.
If the LLC has filed an election with the IRS to be treated as an S corp or C corp for tax purposes, then the treatment would be completely different.
