Online TurboTax does not have "Forms" view--that is only a feature of the desktop software. Your post does not say whether you are using online or desktop.
For online:
When you requested your extension you were supposed to pay your estimated tax due. Did you enter the payment you made into your tax return? Go to Federal>Deductions and Credits>Estimates and Other Taxes Paid>Other Income Taxes This will show up on line 17 of your Form 1040
IF you are using desktop you click on Easy Step and it will switch to Forms mode.
