Since you worked in KS, you will file with KS as well as MD for 2016. (TX has no state income tax so you don't file there.)
*IF* you were still a MD resident while working in KS, you should be able to claim a credit on your MD return for your net income tax paid (NOT withheld) to KS; but you will still have to file a KS return first. Your KS withholding will be applied to your KS tax return.
