For several years, I have noticed a data flow problem between the Federal module and Missouri state module (desktop) that I have addressed with overrides or manual entries to Missouri form MO-A. I'm sending this note in the hope that the underlying issue will finally be fixed.
When a Federal Form 1099-DIV or -INT form includes interest/dividends on federal obligations, the amount is flowing to the Missouri model but is double-counted on line 8a of form MO-A (i.e., $42 on the -DIV or -INT form is reported as $84 on MO-A). I currently fix this with a manual override.
Likewise, when a Federal Form 1099-DIV or -INT form includes interest from states other than Missouri (and the multi-state "XX" code is recorded on the 1099-DIV or -INT form) the amount is not flowing at all to line 1a of form MO-A. I currently fix this with a manual data entry.
