I now have my pin number and agi how do I attach

To add your "IP Pin" received from the IRS. Sign into your return, select "search" in the upper right, and type in "IP PIN". Select "jump to IP PIN" to enter your pin. 

Your AGI will be entered when you go through the "File" section of your return. On step 3 you will be prompted to select an option that you filed last year, and TurboTax will take you to the screen to enter your AGI. 

The IRS has discontinued the e-filing PIN option. https://ttlc.intuit.com/replies/5595740
