If you filed your 2018 return late or amended then the correct AGI may not be in the system. If zero will not work either then you cannot e-file. Your 2019 return will have to be printed, signed and mailed. Rejections do not come from TurboTax--they come from the IRS.
Attach copies of your W-2 and any other documents that show taxes withheld to the left side of the papers where it says "Attach Forms..."
When you print your return, it will print with filing instructions that tell you where to mail it. Pay careful attention to the address you mail your return to —federal and state returns do not get mailed to the same place.
It is not required, but is a good idea, to use a mailing service that will track your return or provide you with a receipt showing that the IRS got it--such as Fedex, UPS, or certified mail.
