After you file

@Joeyfwb - i think we are getting closer, but not yet to the answer.... a few more questions.

 

1) please look at Form 1040 Schedule 2 (look at the upper left corner for the schedule #, title of the form is "additional taxes").  Do you see where the $1400 is coming from? what line number? if it's line 17, please provide the letter (.e.g 17a, 17b, etc). 

 

2) On form 8812, just check that you don't see the $1400 on any line item.  if you do, which ones? if you don't then the IRS letter referencing 8812 is a 'head fake' and the reason for the refund is elsewhere. 

 

3) on Form 1040, please re-confirm that Line 23 on the tax return you submitted shows $1400.

 

post back and hopefully we can figure this out.
