I just had the same experience, Schwab 1099 reporting negative foreign tax. It might be a refund from some previous year, although Schwab doesn't say one way or the other. And yeah, Turbotax won't let me go in by hand and type in a negative number. It's what I'd like to do because another my brokerage reported positive foreign tax, larger in magnitude and I'd like to just combine the negative Schwab number with the positive number from the other place and just claim a reduced but still positive foreign tax credit.
