My company underwent an F-reoganization where my employee stock was bought out as an installment sale. I didn't receive a 1099-B form for this. Where do I report this

I received the first installment on 12/31/2021.  The remainder are 5/2022 and 12/2022.  At this point, I can't figure out how to report this as I will not be receiving a 1099 as per my CFO.
