You need Turbotax Business for the S-Corp. That's a completely different program from TurboTax Home & Business.
TurboTax business is no available as an online product or for MACs. It's for the Windows operating system only. If you purchased TurboTax Businses then you need to download the installation file and install it on your computer.
You will need to complete the business return first, before you can even start your personal return. The S-Corp will issue all owners/shareholders a K-1 which they will require in order to complete their personsl tax return.
