TurboTax Home & Business *CAN* be used to complete a SCH C for a sole propritorship or *single* *member* LLC. If a multi-member LLC or higher, you'll need to use Turbotax Business, which is a completely different program.
Note that in some states that tax personal income, if the only members of the multi-member LLC are a married couple that will be filing a joint return, you "may" be able to file two SCH C's for each married member as a part of your 1040 personal tax return.
