Incorrect State mentioned in Box 15 of W-2

Hello All,

I've incorrect state on the W-2 form (box 15). I've notified the employer but I think it's too late. What would be the procedure now? I've not yet filed taxes.  I heard I need W-2c but my employer won't get that to me until 3-4 weeks so i'll end up missing the deadline. 

I changed jobs and moved to TX from MA in June 2024 but my new employer in TX never updated my MA address to TX. I saw that my W2 with current employer in TX has withheld state tax for MA from June - Dec 2024. How can I get it back and what can I do now to meet the deadline?

For reference, I'm joint filing and my spouse in a nonresident alien.
