How to complete the information the like-kind section 1250?

First you must convert the property in the rental section and note the depreciation. Then you jump to Form 8824 and follow the prompts to enter the information of the house sold and then the house purchased. 

If you purchased more than one house, you will have to do a form 8824 for each new house and pro-rate the house sold among them. If you need help in determining the basis for the new properties, you can see another post of mine here.

For more information about the program and depreciation, see another post of mine here.

Beyond the basics of starting with the rental section and then moving to the 8824, possibly many times, you will need to let us know more about your specific issue.
