is the first place you should go. I helped a good friend through the process last year when I discovered she had foreign bank accounts that had balances above $10K. You will need to go back 6 years, three for amended returns for 2019 through 2021 and three more 2016-2018 in addition to doing your 2022 return. For each year, we filled in at least one form 8938.
It may take some time to assemble the required information, so get working on it as soon as possible.
