The 1040 is the Federal tax form that is completed after you enter all your data and your return is ready to file. Any data that needs to go on the 1040 form is entered with other forms and information you provide by answering the questions in TurboTax.
If you have profit/loss on stocks, mutual funds or bonds, you will receive a 1099-B from your financial institution and that is reported in the Investment section.
If you have a profit/loss from selling your home, that is reported under Less Common Income.
Should you have another type of profit/loss to report, please let me know and I will direct you.
