is this 2 different jobs or is it that it is for 2 different states and double counting the federal income then? If you confirm that, your issue is 1 job didn't know about the other and you overcontributed to your 401k. You will have to contact the administrator of the plan and remove the overfunded principal and related income/loss out this year. You will then get a 2018 1099 related to this but, sadly too late to report it. You will have to adjust your return this year to report the return of principal as otherwise you will have to amend when you get the 1099 for the return of contribution.
I am not a TT employee, I hope this helped.
