w2-C corrected w-2 with missing info in box 1 & 2

[b52bomer]

Client received a completed w-2 and then received a w-2 C corrected, but no amounts were listed in box 1 or box 2
box 3,4,5 & 6 have the previously reported amounts and then the corrected amounts. The client worked one month in 2017 and then 5 months in 2018. The client contacted the employer and was told to use the original w-2 box 1 and 2 amounts and use the w-2 C corrected amounts for box 3,4,5 & 6. The client was told that they would give client credit in 2018. The client quit at the end of May in 2018 but the employer continued to pay client but only after they paid about 20,000 more and repeated calls by the client to stop paying (bank deposit) Client is paying this overage back. Has anyone ever had a situation like this and if so how was it handled. i told the client to call the x employer and this what they advised client to do. This is a first for me, prior w-2C's have always had all boxes 1 thru 6 filled in. Any advice would be appreciated

W-2-C missing information

The employer is probably correct. Enter the amounts from Boxes 1 and 2 from the original W-2.

Leaving the unchanged boxes blank is the correct way for the copy that the employer sends to the Social Security Administration.

It is possible that the employer has the option to fill it in for the copy that they send to the employees (to reduce confusion), but otherwise, the original W-2 numbers are still valid unless the W-2c shows it being changed.
