Here is our most common solution to this issue as adding "0" has not worked for us for our clients.
My recommendation is - Even if you have a copy of your prior years' tax return and you enter the correct amount from Form 1040 line 11 adjusted gross income (AGI) you more likely than not will get rejected due to your AGI not equaling the IRS. This should not happen if on Form 1040 Lines 1 - 8, there is only a dollar amount on line 1 which will be the same amount on line 11. If your return has any dollar amount contained in lines 2b - 8 take the time and go to IRS.gov and for a copy of your transcript as some of these lines appear to be included other sections on the transcript .
Hopefully you've been aware of Form 1040 Line 11 as your AGI. What the IRS appears to have done with the transcripts is shift some of the additional income to different sections on the transcript.
In the case that convinced me to write this reply; the client had W2 income $15,000 (not actual) and Unemployment income $5,000 (not actual). On Form 1040 Line 11 would be $20,000 AGI. The IRS transcript the Income Section includes both numbers, but the $5,000 was then deducted as Other Income. The next section Adjustments to Income total 0, therefore in this case the sum AGI on the transcript was $15,000.
Tax and Credits the next section includes the adjustments etc. totaling the $20,000 however, on the transcript
this line is called TOTAL POSITIVE INCOME PER COMPUTER not AGI.
Our reject therefore was created when we entered the AGI from the 1040 as $20,000 when the transcript AGI line is only $15,000.
I hope this is informative.
