If you have to prepare and file a 1041 (and issue one or more K-1s), then you'll need TurboTax Business software to do that. It's available in CD/Download versions only, and is Windows based. Here's the link: https://turbotax.intuit.com/small-business-taxes/?srqs=null&cid=ppc_gg_b_stan_all_na_Brand-Business_...
But when you say that "I have" a 1041 and K-1, if that means they've already been prepared, then you won't need TurboTax Business to file them. The 1041 can be filed by mail (see page 8 of this link https://www.irs.gov/pub/irs-pdf/i1041.pdf for filing addresses), and the K-1 can be entered into your personal tax return using TurboTax Premier online (or higher).
