Multiple W2s with different box 18 amounts, different box 19 amounts but the same box 20 locality name

This is a very weird situation and I don't know what to do:

An employer paid for relocation from one state to another.  That has generated a total of 4 W2s:

1. One for the departure state
2. Three for the arrival state
   1. The first for the arrival state has box 16, 17, 18 and 19 values with a locality name
   2. The second for the arrival state has no box 16 or 17 values with different box 18 and 19 values but the same box 20 locality name
   3. The third for the arrival state has no box 16 or 17 values with another set of different box 18 and 19 values with the same box 20 locality name
3. TurboTax generates an error message
4. The values cannot be combined in the submitted return because the data will not match the W2s submitted to the IRS or the arrival state
5. The employer has not provided any assistance or direction

What can we do and where can we get accurate information?

Thank you for your help!
