Your home state of Kansas can tax all your income, including what you earned in Missouri.
In addition, Missouri can tax the portion of your income that you earned by working in Missouri.
>>On your Kansas return, you will be able to claim an "other state credit" for the taxes paid to Missouri.
That credit will reduce your taxes due to Kansas. The credit should be significant, given that you "worked mostly in MO." Your KS withholdings may appear to be low, but your KS taxes due are also going to be reduced by the credit amount.
I suggest you enter your W-2 exactly as is. In TurboTax, be sure to complete your non-resident MO tax return first, before you do your home state KS return, so that the program can correctly calculate and apply the credit.
