I answered all the questions and got my tax owed, but I don't know if they got it right. Are there worksheets I can see showing a calculation of income, deductions etc?

Yes, but you have to pay in order to view/print those forms and schedules.  Follow these steps to pay for your return before filing.  You will still be able to make changes prior to filing.  You will be able to print a preliminary copy of your return in TuboTax Online:

• click on "Tax Tools" on the left hand side of your screen.
• From the drop down menu click on "Print Center"
• Click on "Print, save or preview" this year's return
• On the next screen click on "Pay Now"
• Submit your payment information and you will be able to print your 2015 tax returns

Note, you must pay by credit card.  You will not be able to pay using your federal tax return.
