1) On Form 1040 Schedule 2, the $1400 is on line 19 (Additional tax from Schedule 8812)
2) On Schedule 8812, I see $1400 on the following lines:
B1 (Advance child tax credit payments received from Letter 6419- taxpayer)
15e (Aggregation amount of advance child tax credit payments …)
28a (Enter the amount from line 14f or line 15e)
29 (Excess advance child tax credit payments …)
40 (Subtract line 39 from 29)
3) On Form 1040, Line 23 (Other taxes, including SE tax, from Schedule 2, line 21) does indeed show $1400
