If you have a single-member LLC it is disregarded for income tax purposes. Since it's disregarded, you do not indicate anywhere in your tax return that it is an LLC. That's why TurboTax doesn't ask. You just file your business as a sole proprietorship, which is probably what you have done in past years. Just continue doing that.
If you have a multi-member LLC, or if your LLC has filed Form 8832 to elect to be treated as a C corporation or Form 2553 to elect to be treated as an S corporation for tax purposes, the LLC has to file its own tax return, separate from your personal tax return. You cannot use TurboTax Home & Business to file the tax return for the LLC in these situations. You have to use TurboTax Business, which is different from Home & Business.
