I'm sorry.  What part of my answer was not helpful?

I see that part of my question didn’t post. It should read that all of my state taxes on my paychecks were paid to Missouri when they should have been paid to Illinois. Now my w-2 has all my income as being made in Missouri when half of it was made in Illinois. My company payroll person and the company that does our payroll has been informed of this for two months and I have yet to get answers from them.

The payroll company isn't likely to correct this for you as it requires them to file amended forms to both the IRS and the states involved.  However, you can correct this issue yourself by filing two Part-year resident returns, one for Missouri and one for Illinois.  Part-year returns allow you to allocate (divide up) the income according to where you lived when you earned it.  You said there was a change of payroll companies when you moved to Illinois, so you can determine your wages by state yourself.

You will most likely end up getting a refund from Missouri and you will have to pay over the Illinois tax yourself.  Don't forget the due date for your payment to Illinois is April 15, 2019, but if you file Missouri soon and select direct deposit of your refund, you may have the money in time to pay Illinois.

I lived in Illinois all year. How would that change it? Or would it change it? I live on the state border so I can travel daily for work.

Illinois Resident return.  Missouri Non-Resident return.  Even easier - be sure to do the Missouri return first.

So I’m not going to have issues in the future if I don’t have the w-2 corrected?  That’s my real fear. I don’t want to have the state come back at me for it.
