Do not bring it inside. It is an outdoor tree and needs cold so it gets a proper dormant period.
You do need to protect from excessive wind and extreme cold.
The best options to winter an outdoor tree on Long Island are
An unheated shed or garage. With both of these methods, you need to check your tree for watering needs at least once a week and water when necessary (when the soil is almost dry).
Mulched against the foundation of the house, preferably the northern or eastern side. The residual warmth coming from the foundation will help keep the tree at a good temperature.
You can use pine bark chips as mulch and you can use leaves as mulch. I have a couple of trees that are too tall for my coldframe mulched against the north side of my house in leaves.
Ideally you can get some plastic landscaping fence and a 3-4 metal fence posts. Make a little fenced in area against your house. Put the trees in and fill in around the trees with leaves.
Be careful not to break any branches when you do this.
