Notice recieved

[JEBRITT]

I received a notice stating, "There is a disagreement between the W-2 form(s) filed and the one(s) submitted to the department. Line 1 and/or line 13 were adjusted accordingly. If you disagree, please submit a letter from your employer's payroll office to confirm the wages and withholding that you input on your tax return are correct."
What the heck does this mean? Everything looks the same. What do I do to recieved my refund?

Check with your employer to be sure a corrected W-2 was not sent to the IRS and not to you. If not, contact the IRS.
