Foreign Tax Credit: withheld vs paid taxes

[celiam]

TurboTax asks me for “tax paid” on each of my foreign employment slips. My foreign slips only list withholding amounts, so that is what I entered.

I need to subtract my foreign tax refund from these numbers, but there is no way to plausibly do this on each individual slip. I only have the total foreign tax paid for the year (after refund).

There is a field on the FTC page called “foreign tax paid on employment income”. It seems like this would be the place to specify the actual amount paid after the refund. However just under it lists the amount reported on slips, which is much larger (as that does not take the refund into account).

This discrepancy doesn’t seem right. I think I am missing an extra step to demonstrate the difference between tax withheld and what was actually paid in the end.

Any ideas of how to report this properly? Do I need to somehow determine the foreign tax paid, not withheld, for each individual slip, even though I am not given this information? Thanks in advance!
