Indexing and TDS has nothing to do with US taxes, so they don't affect your US tax return.
After converting the purchase price and sales price to US dollars, if there is a gain you will need to report that gain on your US tax return.
If you have a mortgage on the property or if the property has been used as a rental property, I highly suggest that you go to a tax professional that is experienced with US tax from international sources.
Don't forget FBAR and FATCA forms, if they apply. If you have not been filing those in the past (if they apply), I highly recommend going to a tax professional that is experienced with correcting those prior missed forms.
