Yes. A single-member LLC files an extension using Form 4868 (same as your personal return). An extension gives you more time to file, not to pay, so any estimated tax is still due by the original deadline. If you want to make changes or add a document to a tax return that has already been filed and accepted by the taxing agency, you should follow these guidelines. You must first wait until the initial return is completely processed. This means waiting until the payment submitted with the tax return has been processed, or your refund has been received. You will have to use the same TurboTax account that you used for the original tax return. Once you begin your amendment, you'll see your original return. The refund calculator will start new at $0 and only reflect the changes in the refund or tax due Only make changes to the areas of your return that need to be corrected. You have three years from the date you filed your return or two years after you paid the tax due (whichever is later) to file an amendment
