Prime and 2023 EV tax credit + new Prime accessories

Long story short, my beloved Prius Gen3 got totaled and I'm looking for a newer one.

Out on the main Gen4 forum, MalachiNG smartly suggested that I also consider a Prime and after reading tons of posts on this forum I couldn't agree more. I will be driving a lot, including at night, and outside of the missing spare tire the Prime is almost certainly a better choice for me.

Further research showed that the IRS does indeed consider models 2017-21 qualified for the up to $4,000 tax credit for FY23:
Used Clean Vehicle Credit | Internal Revenue Service
Manufacturers and Models of Qualified Used Clean Vehicles | Internal Revenue Service

1) I am curious to know if anyone in this community has done this yet. I must say that "the dealer reports required information to you at the time of sale and to the IRS" has me slightly worried as I see no specific forms listed by the IRS for both the transaction with the customer and the report to the IRS. What do they use? A blank sheet of paper?

2) Just for my peace of mind, am I correct that the HV batt capacity on the Prime is 8.79Kwh?

3) Does anyone know if the 4K tax credit applies to the entire tax earnings for joint filers, or is it only available for the amount earned by the one spouse who buys a used Prime? (sorry for the dumb Q, taxes are not my field of expertise...)

On another note, in addition the owner's manual, what are all the accessories that come standard with a Prime? I'm asking because I've seen a few listings where the dealer lists nothing. I also called a place where the sales guy was entirely clueless about this.

 

Thanks for the tax bit.

As to the doc you listed, it refers to new vehicles. I posted the IRS doc for used ones in my OP.

FWIW I will more than likely get a 2017 Prime with low--ish mileage as more recent models sell at utterly ridiculous prices.

 

This makes sense. Thank you.
