@jgwilliamssnowbird Do you need to prepare a 1120S Business return or did you get a K-1 from it?
You need Turbo Tax Business.
TT Business is for 1120 Corporation, 1120S Corp, 1065 Partnership or 1041 Estate/Trust returns and will not do your personal 1040 return. It is a separate program from the Desktop Home & Business program or the Online Self Employed version.
You will get a schedule K-1 (or a W2) from the business return to manually enter into your personal 1040 return.
Turbo Tax Business is not available to do online or on a Mac. You can buy the Window's (Win 7 or newer) version here. And you can have both TT Business and TT Home & Business (or any personal version) installed on your computer at the same time.
