Since the same issue is occurring with multiple international funds in this fund family, I suspect there might be a holding period, or similar issue, that makes the 1099 1b amount different from the supplementary material amount.
Probably the long-term solution would be to update TurboTax so that one could further adjust/modify/customize the F1116 box 1 final amount, and have the program ignore the calculated amount. Perhaps in future years, I suppose.
In the meantime, I am inclined to agree with your suggested solution. Technically, it's inaccurate, but the amount is small, and the odds of the IRS noticing or caring is small (because the tax liability is overestimated).
In any event, thanks for your replies, I appreciate it! 🙂
