I have to amend my 2020 return as I made a big error. Unfortunately I did not realize the error until after I hit the transmit button. I had saved the e-filed return before I transmitted it, but upon seeing the $16000 error I went in and found the problem and fixed it.
Now I need to amend the return, but the corrections I made overwrote the erroneous return, so I don't have a copy of it. What do I do? Instead of a $5265 refund, I have a tax due of $10,613, so I need to get the amended return to the IRS by April 15.
How can I find a copy of the return that was filed so that I can re-create the incorrect return?
