If you are e-filing, you don't physically sign it; you use your 2018 AGI to "digitally" sign it. There are a few places you can get your 2018 AGI:
- If you filed your 2018 taxes with TurboTax, sign in and go down to Your tax returns & documents. Select View adjusted gross income (AGI).
- If you didn’t file your taxes with TurboTax in 2018, the best place to get last year's AGI is from the 1040 form you filed with the IRS. Look on page 2, line 7. If you filed a 1040NR, it'll be on line 35.
- If you're having trouble locating your 2018 return, the second-best place to get your AGI is from the IRS. You can order a free transcript of your return at the IRS Get Transcript site or you can purchase a full copy of your 2018 return. Both versions will include your AGI.
You won't find your AGI on your W-2 or 1099 form because those forms don't take into account over a dozen above-the-line deductions that go into calculating your AGI.

When you get to the last page where you are to enter a 5 digit "signature" you cannot put in letters, only numbers. If you try to put in letters, the box will remain red and won't allow you to type.
