@Dennis8 , I have downloaded / CD version of TurboTax Home & Business --- thus I can create your scenario of US stocks sold in the USA for capital gain ( long-term ) and taxed in Mexico at 15%. It works but you have to be careful because it does not ask for the foreign tax percentage etc --- you kind of have to work out the gross income ( Capital Gain ) from the Mexico Tax filings ( or your own records ), multiply by the factors called out by IRS and then enter this as your gross subject to foreign taxation for this category --- then tell TurboTax the actual taxes paid and go on from there. In my case because of the software on my machine , I could go back to forms mode and confirm that the form 1116 was properly filled out.
Hope this helps
If you need more help on this -- let me know.
Note : here we are actually resourcing the US capital gains to MX so that the foreign tax credit could be applied to avoid/mitigate double taxation
