Do I enter property taxes, home insurance , for a vacation home in the primary section for my main home. ? Can I enter repair and improvements for the vacation home too?

List the property taxes as an itemized deduction separate from your principle residence.

The home owners insurance is a personal expense and not deductible; as are the repairs and any maintenance.

Keep track of the improvements as they will be added to the cost of the property to determine your basis when you ultimately sell the home.
