TT has worksheets for everything ( and even some worksheets for the worksheets) so review the worksheet in question to see what it does and what form it supports ... better still just review the forms and ignore the worksheets unless you need supporting details for an entry on the forms.
You can peek at only the Federal form 1040 and the summary of the
state info by going here:
1) lower- Left side of the
screen...click to the left side of the "Tax Tools" text selection.
2) then select "Tools"
3) then select "View Tax Summary"
from the pop-up
4) then back to the left-side and
"Preview 1040"
Then hit the "Back" on the left side
to get back to your tax entries.
To view your entire return using the online editions (including the state) before you file, you will need to pay for your online account.
To pay the TurboTax online account fees by credit card, without completing the 2017 return at this time, click on Tax Tools >>> Tools and then Print Center. Then click on Print, save or preview this year's return. On the next page, to pay by credit card, click Continue. On the next screen it will ask if you want Audit Defense, if you do not want this option just click on the Continue button. The next screen will ask for all your credit card information so you can pay for the account.
