Yes to all above. An LLC is considered a disregarded entity, which means a business entity with one owner that is not recognized for tax purposes as an entity separate from its owner. You have a choice on how you wish to be taxed, as a Sole Proprietorship or as a Corporation. Once you choose to be taxed as a corporation, you have to file a business return, on the Business program.
If you choose Sole Proprietor, then you can continue to use Home and Business. It is much easier, tax-wise to have an SP. However, you may potentially avoid some SE tax by having a portion of your income on a Form K-1S as an S-Corp.
You would have to elect as a Corporation and then file Form 2553.
