We are also stuck on this same issue (married filing jointly), Kansas resident. Perhaps the issue is what Missouri defines as "Missouri source" income? Right now, federal W-2's are entered correctly, with different numbers in box 1 and 16 for both of us. Box 16 has two numbers, one for KS and the other for MO, which add up to Box 1. This seems all correct.
It seems to be hung up on the fact that my spouse's Box 16 for KS is higher (87k) than Box 16 for MO (6k). Box 1 is (93k). For reference, mine is KS (43k), MO (56k), Box 1 (99k).
@RobertB4444 @MarilynG1 For the remote work income, should we be entering in the number from MO, Box 16 OR the number from Box 1?
