Did you have your tax return prepared at an H&R Block office, or did you prepare it yourself with the H&R Block software?
Your 2015 AGI is on your copy of your H&R Block tax return. It's on Form 1040 line 37, Form 1040A line 21, or Form 1040EZ line 4.
If you do not have your copy of your 2015 tax return, and you filed at an H&R Block office, contact that office to get another copy. If you used the H&R Block software, go to their web site or contact their support to find out how to get a copy.
You can also get a free transcript of your 2015 tax return from the IRS at the following link. The Tax Return Transcript will show your AGI (Adjusted Gross Income).
