Retirement tax questions

I guess what confuses me is my Pension and my SSDI are input into my Federal Tax Return but when I do the State through TT, only the SSDI is carrying through and reported to the state.  When I was having state taken from my Pension, I kept getting it all back so it was recommended I stop paying out to the state so now, I don't owe anything (nor get anything back) but its not using the Pension in the calculation.  Just nervous.
