If I can carryback my $403 of excess foreign tax credit in 2017 to 2016 amend, how do I enter this in 2017 1116 Wks so that the $403 carryforward dissapears?

$403 excess foreign tax credit that I shows as carryforward in 2017.

I qualify to get the carryback in 2016.

I know I can amend 2016 and get the total credit.

The question is specific on how to account for this carryback in 2017 so the carryforward dissapears.
