Hello. I don’t understand where you want to put the annote
field, but here it is in bibliography:
#let bib = ```bib
@misc{CMS2024,
author = {Last Name, First Middle},
title = {Fiscal year 2024 improper payments fact sheet},
url = {https://www.cms.gov/newsroom/fact-sheets/fiscal-year-2024-improper-payments-fact-sheet},
annote = {The total estimated improper payments for Fiscal Year 2024 across Medicare and Medicaid programs was approximately $85.45 billion, including $31.70 billion from Medicare Fee-for-Service, $19.07 billion from Medicare Part C, $3.58 billion from Medicare Part D, and \$31.10 billion from Medicaid. Published June 4, 2024. Accessed April 1, 2025.}
}

#bibliography(bytes(bib), style: bytes(csl))
There is some weird interaction with dollar signs, since it can directly insert math mode stuff, so not sure how to properly escape them.
This field is special, see Remove the `annote` field from the data model by reknih · Pull Request #220 · typst/hayagriva · GitHub.
You also forgot to use a code block with language identifier, in this case it’s bib
.
