Hi. I just filed tax return yesterday. I have a small llc. How do i know if i filed llc or personal return. If it is personal. Do i need to send one extra for my llc ?

You most likely filed your personal return if you included all of your income and deductions, dependents, and personal filing status.  Also, if you filed your return using TurboTax Online, then you filed your personal return.

Whether you need to file a separate return for your LLC depends on how it was originally formed.  If it is a single-member LLC where you are the only person involved in the business, then you would file Schedule C for the LLC as part of your personal tax return.  There would not be a separate return required.

If the LLC was formed as a partnership or S-Corp, then a separate return for that entity will be required.  TurboTax Business can be used for those returns.
