MD resident with K-1 from both MD and DC. Activated nonresident in Federal and apportioned income. Numbers not transferring to DC D-40 so entered them on DC Allocation worksheet and it's not activating either. DC is trying to tax on 100% of Federal income. Tried doing a subtraction of income and it still taxes as if it's 100% DC. What am I doing wrong?

This is NOT the DC D-40B Request for Refund as it's not wages. It's also not a D-3 Unincorporated Business Franchise Return.  It's just a K-1.
