Q. Or are the parts we paid out of our owner construction loan not reported?
A. Yes. Nothing is reported about this to the IRS, either on your tax return or a 1099.
If you are only building your home, you do not issue a 1099 to your contractor. Only businesses issue 1099's, not individuals.
But, as others have said, you keep good records on your cost, for the future. Invoices form the contractor and copies of your cancelled checks should be sufficient.
