After you file

We only got $4200 of the $5600 we should have received per the IRS (being $1400 x 4 people here). So on my line 30, it put the difference between what we should have gotten, minus what we did receive total. 

 

But now I got a letter saying that line 30 is wrong and I owe the $1400 listed on Line 30, + interest, to the IRS. 

 

UGH!
