How much do other countries owe the US?

I’ve been struggling to find the amount of money owed to the United States from other indebted nations. Does anybody know where I would be able to locate this information? I was able to come across this article which was written back in 1921. Not sure if we’ve been paid yet but with inflation it seems to be pretty significant not in the trillions but still significant.
