TurboTax Premier is used to create a personal tax return (Form 1040). This version does not produce Schedule K-1. For that, you would need to create a business return using TurboTax Business.
However, if you need to enter a Schedule K-1 that you received from an investment, you will find that under Federal Taxes >> Business Items >> Schedules K-1 >> Start/Update. Or search on "schedule k-1" and use the jump-to link to go directly to that section of TurboTax.
