For what year? It's to early to file 2019. And it's too late to efile 2018 and prior. Efiling closed back on Oct. 15. So you have to print and mail 2018 now. You don't need the AGI to print and mail.
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. Don’t forget state.
