414(h) employee contributions in W-2 Box 12 Code D

My wife has access to the TCRS K-12 Legacy plan which seems to be categorized as a 414(h) under the IRS code. Last year and this year, her mandated employee contributions to this plan were included in Box 12 Code D on her W-2 which seems to be only for 401(k) contributions. For 6 years prior to 2018, where she also qualified for this plan, her mandated contributions were not reported in Box 12 Code D but in Box 14 instead.

 

In 2019, she also had access to a 401(k) which she maxed out. So, her 2019 W-2 has ~$22,000 in Box 12 Code D [$19k 401(k) + ~$3k TCRS]. TurboTax throws a warning because this is greater than the expected max.

 

Her payroll department has been researching this for several weeks, but does this seem like an error? Should these 414(h) contributions appear in Box 12?

 

If we are not able to get a revised W-2, how should we address this on our tax return?

 

Thanks.
