Thank you but that doesn't seem to affect the result.  To elaborate, client has $113,150 in taxable IRA distributions--$67,600 in MT and $45,550 in AZ all coded by state in screen 13.1.  Lacerte apportions $75,433 to MT based on 8/12ths period of residency--.66666667 whereas AZ receives $45,550 based on the state entry coding.  This inconsistency results in an overstatement of $7,833 of pension income on the state returns.  I want Lacerte to include MT income by state coding on screen 13.1 not by using some formula allocation.
