Are you referring to foreign-source qualified dividends and CGD?  If so, ProConnect Tax does make the necessary adjustments when the conditions for exception are not met.  If the conditions are met, however, it assumes an election not to adjust will be made.  Either way, you'd find an informational diagnostic about that.

On the other hand, if your client has foreign-source capital gains/losses, you will need to compute the necessary adjustments offline and plug them in under Credits > Foreign Tax Credit (1116).

Part of the problem is that ProConnect Tax has not been programmed to identify whether CG/CL on Sch D is US or foreign source.  And, heck, it won't even know your breakdown for gains vs losses when you choose to enter a lump sum for summary attachment (e.g. from Consolidated 1099), so you will need to do the grunt work yourself.  Again, ProConnect Tax will generate an informational diagnostic to remind you that's something you need to consider if it applies to your client.
