can you restate your issue and question?
if you did not report the stimulus money, which means there is a number now listed on Line 30 that should not be there. do not do anything, the IRS will catch that and adjust the return without the need to amend.
is there a 2nd issue with your return? what does 'report income' mean - or is that the stimulus you are refering to?
If you have an incorrect amount on the 1040 line 30 the IRS will correct this for you automatically. There is nothing you need to do.
I couldnt recall getting the 1400 stimulus payment so I put 0 or no on that. Then after filing I found I had received it.
@skol44 - again, nothing for you to do; the IRS will find the error and reduce your refund submitted on your tax return by the $1400,,,,,
