W-2 may be wrong? What to do now?

in 2021 my husband worked for one company but part of the year in GA and part in TN and has residency in AL.  The company sent  3  w-2s. They have the wages, fed tax withheld, SS wages and tax withheld, and Medicare wages and tax withheld  being EXACTLY the same. The difference is that down in the state area, one is for GA and the other for AL (TN does not have state income tax), and one is for TN with no state taxes taken. To use easy numbers as an example, instead of looking like he made $100 total all year it looks like he made a total of $300! It looks like he earned $100 in GA, $100 in TN, and $100 in AL (via no tax TN). What do we need to do so we can get this fixed and file taxes?
