If the code is IND-032-04 for AGI you will have to go to the IRS site to get what they have on record as your prior year AGI. My TurboTax return was not correct because the IRS corrected my return and sent a letter informing me of that. What TurboTax had on file was not correct but I went to the IRS site and got the AGI they had on file.
Just a note, if you do not have a sign-in for the IRS site you can enroll but it is a long process (about 20 minutes) with pics of your drivers license needed (front and back) and a selfie but you will eventually get your sign-on.
