I have a schedule k-1(Form 1041) deduction. Where do I input this number?

Using the online editions to enter a Schedule K-1 you would need to upgrade to either the Premier or Self-Employed editions.

To enter a Schedule K-1

• Click on Federal Taxes (Personal using Home and Business)
• Click on Wages and Income (Personal Income using Home and Business)
• Click on I'll choose what I work on (if shown)
• Scroll down to Business Items (Business Investment and Estate/Trust Income using Home and Business)
• On Schedule K-1, click on the start or update button
