If you used TurboTax, you can access your return by logging in using the same TurboTax account that you used to file your previous return. Please see How do I access a prior-year return? for instructions.
If you just need your AGI, you can also get it by obtaining an online tax return transcript from the IRS. Please see Can I get a copy of my tax return from the IRS? for more information.
