One of the last questions under the deductions and credits section is "Just checking if you're a homeowner?".
How should I answer this question if I own a home, but rent it out and have entered the property taxes, interest in other areas of the program?
See screenshot please.
The simplest thing to do is to answer 'No' you are not a home-owner.
The question is really referring to whether you own the home that you live in, not whether you own a rental property. If you answer 'Yes', you will be asked to enter information about your primary residence that would not apply to your situation.
