When reporting on schedule C, you will be reporting the total of your income. Keep supporting lists and details for you to explain how you came up with your totals. If a form was received 1099S when the property was sold, thenn enter that as part of your income using that document to show the details. Also include the income received on properties where no form was received. You will not be listing the property information for those properties since there was no form was received; however, the income would still be reported as part of your gross income. Example would be - if you sold 5 properties, received 2 1099S forms, then you would be inputting the forms received, then adjust your total income to include the total amount received upon the sale of the properties for which no form was received.
