Incorrect HSA contributions on W-2, but former employer refuses to issue W-2C

I maximized the HSA contributions in 2023 within the IRS limit, but my former employer made a mistake on W-2 box 12, code W, they added $200, now on record I over contributed $150.

 

The simplest way to resolve this issue is to ask my former employer to issue a W-2C, but they refused to do so. 

Both my pay stubs and HSA account statement shows the correct number $1779, but it is $1979 on W-2 box 12.

 

How do I resolve this on TurboTax? I'm using TurboTax Home & Business Mac version.

 

Thank you so much for the help.
