Thanks for the response Kris.
I've reached out to Tesla to see if they can change the form.
Based on this line from the IRS website (https://www.irs.gov/newsroom/topic-b-frequently-asked-questions-about-income-and-price-limitations-f...)
"If your filing status changes between the preceding year and the current year, you may claim the new clean vehicle credit if your modified AGI is less than or equal to the threshold applicable to your filing status for in the preceding year or current year."
I'm interpreting this in my case as, if your filing status changed from MFS 2022 to MFJ 2023, you may claim the credit if your MFS AGI in year 2022 is less than the threshold of 150k for MFS. So if my wife's MFS AGI in 2022 is under 150k, she can claim the credit when we file jointly in 2023.
Is that correct? I'm stuck on the "modified AGI" line, If her AGI is less than 150k in 2022, will that be modified in any way if we MFJ in 2023?
