Clergy Housing Allowance

My husband is a clergy person.  Over the past few years our taxes have been done by a CPA.  The CPA used a "Schedule 1 (Form 10400) Additional Income and Adjustments to Income" to document the housing allowance.  Last year, with a turbotax person we found how to enter that form.  This year I can seem to find a way to access it.  What do I do?
