@pankajshah66 -- Namaste Pankaj ji.
Need more info to be able to answer with any specificity:
(a) Are you a US person ( citizen/ GreenCard/ Resident for Tax Purposes )/
(b) How did you acquire the property ( bought, inherited or what ? )?
(c) When did you acquire the property? When did you dispose of the prop?
(d) What type of property -- (residential or land or what ?) ?
(e) How was the prop. used during the holding period ? Specifically if the property was used a income / rental then did you recognize the depreciation?
(f) Assuming that TDS was at 20%, were you planning the indexing or without indexing ?
I am assuming that the property was in India ( a country with whom US does have a Tax Treaty ).
Also are yopu using a windows download ( my favorite being Home & Business for covering complex scenarios )?
I will circle back once I hear from you . You can also PM me ( if uncomfortable answering on this public forum )
