@jkbasak , starting with your last question --
(a) I am a volunteer in the community, have no other relationship / interest with TurboTax. No you cannot reach me through TurboTax support -- Post in the community or PM.
(b) your point 1, is generally correct except for travel expenses ( it is generally hard to justify this and win the argument ). Generally what you are doing for US purposes , is to treat the sale as if was a domestic property. So you adjust your basis in the property as shown in my earlier answer . Tell TurboTax that you have sold a home/ residential property / second home etc. ( as the case may be ) -- if the property was for personal use and not income then this will be under personal income, go down the list of incomes and select appropriate one, If the ;property was an income property i.e. rented out and possibly depreciable then this is generally under Business Income. What you are doing here is just recognizing a sale and ONLY under US tax laws.
(c) your point 2 --- if and only if you wish to claim Foreign Tax Credit -- form 1116. This is under Deductions & Credits-- select "Foreign Tax Credit" and TurboTax will walk you through filling out the form 1116. Here your Foreign Source income is your gross foreign income ( before TDS ) subject to US taxers -- it is mostly the lesser of the foreign capital gain and the US capital gain. This is where you also enter the final Taxes paid to the foreign taxing authority. Because TDS is only a withholding, one should generally wait till the Foreign tax amount is finalized or one may have to amend the US return.
Note here that while US has a treaty ( Double Taxation elimination/mitigation ) with India , most states do NOT recognize foreign tax treaties and therefore your capital gain ( per US tax rules ) may flow to the State return and be taxed -- no foreign tax credit.
Have I answered and cleared your doubts or did I confuse the situation more ? As I said earlier , you can always PM me for more specific interaction ( just NO PII --- personally Identifiable Information ).
Namaste ji
