Im in the 2021 trust module and getting an error message. It says I need to attached a Schedule B for the carryover.

Where can we get this form? I go to the instructions and see no Schedule B. 

There is no worksheet in lacerte. 

New Schedule B (Form 1116), Foreign Tax Carryover Reconciliation Schedule.

 There is a new Schedule B (Form 1116) which is used to reconcile your prior year foreign tax carryover with your current year foreign tax carryover. This new schedule replaces the previous attachment requirement for Part III, line 10. See Schedule B (Form 1116) and its instructions, and the instructions for line 10 later, for more information.
