@shyamparashar - let's roll this back as I think some in the Community may has misinterpresed your issue
1) if there were 3 people in your holdhold, you were eligible for $4200 which should have been delivered to you either via a stimulus payment in the March - May, 2021 timeframe. If your bank records show you received it, no 1040X is necessary, You are done!
2) But if you didn't receive it, you were to answer the TT questions saying you didn't receive the $4200, which would have placed $4200 on Line 30 of Form 1040.
if you have $4200 on Line 30, then you are done as no 1040X is necessary,.
But is you did not receive the stimulus payment of $4200 and Line 30 shows zero, then YES, you need to file a 1040X
for others: the IRS took the position of Heads it wins and Tails it wins! if Line 30 overstated what was owed, then the IRS adjusted Line 30 down to the appropriate amount. But if Line 30 understanded what was owed, it did NOTHING and expects the taxpayer to submit a Form 1040X
@fanfare suggested approach makes sense!
