@girigiri , having read through the thread what I get is that you have paid US$xxx as taxes to India on income US$YYYY for the Indian Tax year 04/01/2022 through 03/31/2023 and that you would like to ameliorate the effects of double taxation per US/India Tax Treaty. You are a US person ( Citizen/ GreenCard/ Resident for Tax purposes ).
1. The first item I would like to make sure that you have allocated the foreign income and the taxes paid i.e. you have annualize the income and the taxes levied/paid from the Indian Tax year to US Calendar year.
2. Really need more details as to what the foreign incomes were i.e. what was the allocated incomes by category -- interest , dividend and of course capital gain
3. Once we have allocated in comes for the year , you can generally allocate the taxes ratiometrically i.e. a straight line ( even though that may not be actually true but that is the best one can do unless it is actually possible to show that the interest income was taxed at a different rate than the capital gain for example.
As you can see from the above we need more info to be able to help you . IRS is not looking for an airtight logic but consistent logic and best effort to harmonize between different tax systems .
I will circle back once I hear from you
Sorry for the delay in responding
