@SingerHiker , agreeing with my colleagues @Opus 17 & @Anonymous_ on steps to take to regularize the monies from your account in a foreign country.
While it may be slightly "off" , but I would report/recognize all the growth in that account in the year that you found out that the account was still valid. This is especially true since the total amount is reasonable ( corpus + growth = US$17XX) and the growth has been for a number of years. Additionally I would keep all the paperwork from the foreign bank that you received this year ( to show that these were received ONLY this year and that you took action to correct your tax records ). What you are trying to show is that there was No intent to hide income.
That is my two cents.
