Since you are working on a 2017 return, be aware that it cannot be e-filed. So when it asks for your 2016 AGI it will not matter. Your 2017 return has to be printed, signed and mailed.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return.
