My prior years returns are not showing up on my documents. My old computer where all my stuff was stored is not recoverable at this point and I can't get to any of my PDFs at all. I have no way to see my old AGI.
You can try putting 0 in the AGI
box, it has gotten many people through since this is a new feature it
is not 100% fool proof yet. You can also use some of the information
below if that does not work for you.
You can always get a Tax Transcript from the IRS. Here is the link to that page in their website. https://www.irs.gov/individuals/get-transcript
If you choose to get a tax transcript, I would suggest filing an extension to get you more time.An IRS extension gives you until October 16 to file, but it doesn't give you until October to pay your taxes. Those are still due by midnight, April 18.
(Expecting a refund? You may not need an extension. Read more here.)
