I'm unable to get my ip pin tonight, my taxes were rejected because of this, do i need to file an extension?

Yes, you need to file an extension. 

To file Form 4868 to request an extension on time to file your tax return, select your situation:

• TurboTax Online: follow these instructions to e-file your extension.
• TurboTax CD/Download software: follow these instructions to print Form 4868.

Keep in mind: An extension doesn't give you extra time to pay your taxes, but it'll keep you from getting a late filing penalty. (You'll still owe interest if you pay after the deadline.)

Yes, you need to file an extension.

If you owe taxes, suggest you pay using https://www.irs.gov/payments to avoid the interest penalty.
