The extension form is totally unneeded since it has nothing to do with the actual return and is not attached to the tax return filing.    The only thing from that form that is reported on the tax return is any amount you may have paid with the extension and that figure you should have from your bank records.

Here's how to navigate in Online TurboTax to the place to enter the extension payment you made so you get credit for it on your return.   If you used TurboTax to file the extension, it *might* be pre populated, but you should check anyway.

• Under the Federal Taxes tab (or Personal tab in Home and Business)
• Click sub tab "Deductions & Credits."
• "I'll choose what I work on." (or it may say "All tax breaks.")
• Scroll down to topic "Estimates and Other Taxes Paid."
• Find subtopic OTHER INCOME TAXES, and click START or Revisit.
• On the "Other Income Taxes" screen choose the type of extension payment you made and click START (or Update). Be sure you choose the correct year.
• Continue the rest of that section.

Once you have entered the extension payment (or confirmed it if it's pre populated), then before filing verify that you are getting credit for it.     

A state extension payment is entered in the same navigation steps as above. If applicable, verify that it appears on the state return prior to filing.
