Where can I find form 1033, a form to defer capital gains tax on a gain received due to the casualty loss of a property?

I sold a rental property in 2017 due to the total loss of the building on the property. I plan to replace the property with another rental property of like or greater value and would like to defer the capital gains on the property with the replacement. I have been advised to file a form 1033 instead of a 1031 as the property was sold due to the total loss of the building on the property, not a voluntary sale of the property.I
