Where do you think it's relevant?

Foreign tax credit

Qualified Business Income Deduction

Passive Loss

163(j) limits

Something else

I would think Foreign tax credit

Apart from this, does client have foreign income and foreign tax paid or accrued?

If no, fuggaboutit.

If yes, poke around in the 1116 credits screen for an entry place.

Thanks.  I think I found it at the bottom of the Deduction and Losses section of the credit screen.
