Yes there is a Desktop program. You need the Turbo Tax Business Desktop program. It is a separate program from Home & Business. It is not available to do online or on a Mac. And it will not do your personal 1040 return. You can have both Turbo Tax Business and a personal version (like Home & Business) installed at the same time.
You can buy the Window's version here…..

You will need to amend your personal 1040 to remove Schedule C and to add the K-1 you will get from the Business return. So wait to amend until the Business return is done.
