@mickeydude , Agreeing with the excellent response from my colleague @AmyC on the foreign tax credit carryover/ carryback, I am surprised at the 20% credit figure. Did you already file the ITR ? I ask because I thought per the new Capital gains determination rules you can use the old indexation path with 20% tax slab or the 12.5% slab with no indexation of basis. So are you talking about TDS amount of actual ITR with the best path ? Just curious.
Note that Foreign Tax Credit allowed will never be more than US tax on the same doubly taxed income ( per the tax treaty ).
Is there more one of us can do for you ?
