Recording the proceeds from the sale of a 2nd home which was not mine.
My Dad purchased a home (paid cash) for my sister to live in 2015. He added mine and my sisters name to the deed along with his. Sold the house in 2020 and I received a 1099-S form for 1/3 value of the sale. However I did not receive any money from the sale, it was all his. What do I put in the cost basis field (amount paid). I didn't pay anything towards the house myself (and in reality I didn't receive anything when it sold) If I use the full amount he paid, it's showing a capital loss (example he paid 125K, sold for 150K, I'm having to report 50K in tax from the sale, so showing a loss of 75K). I am checking the box "some (or all) of the proceeds from this sale do not belong to me. There is an option for Adjustment to gain or loss (leave blank if this belongs entirely to someone else). So I'm leaving blank, but still showing a capital loss? Any advise on these fields and the proper way to enter?? Thank you!
