Where should I add "Property capital gain" info while filing tax using turbo tax ?

[ColeenD3]

You don't just add the gain to a form. You need to go through the interview process. If you sold items that should go on Schedule D, enter your information in the Investment section.

Under Wages and Income, scroll down to Investments. You can enter your 1099-B or any other capital asset you sold.

@ColeenD3 is correct.  You will have to post it in the investment section:

Go to Wages & Income

1. Scroll to Investments and Savings
2. Select Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B)
3. Time to kick off your investments! = Okay
4. Time to kick off your investments! = Continue
5. Let's import your tax info = Enter a different way
6. There are five boxes available
   1. Interest
   2. Dividends
   3. Stocks, Bonds, Mutual Funds
   4. Cryptocurrency
   5. Other
7. You will select Other

You will then go through an interview process to describe the sale.
