DC requires you to send your 1040 and 1040 - A to them when you submit your DC taxes. I should send the "real" MFJ tax return or the "mock" MFS tax return to DC?

This article is helpful about how to do married filing jointly for federal and married filing separately for states (we live and work in different states.) https://ttlc.intuit.com/questions/1901214-how-do-i-prepare-a-joint-federal-return-and-separate-state... I followed these instructions verbatim and am now largely good to go. However, DC requires you to send your 1040 and your 1040 - A to them when you submit your "state" (aka DC) taxes. Should I send the "real" MFJ tax return or the "mock" MFS tax return to DC with my DC tax submission?

You'll need to send in the "real" Form 1040/A -- the joint return that you submit to the federal government -- to DC, as opposed to the mock separate returns.  The mock returns were created strictly for you to prepare your DC returns, and not for submission, but you should retain them for your own records.
