Where do I add that I bought a house inside my taxes I can’t find it

If you purchased a personal residence in 2025 the purchase is not reported on a tax return.  Only when you sell the home would it be entered on a tax return.

As @DoninGA mentions, you do not specifically report anything to indicate you bought a home.

Just remember to enter the expenses related to your home if you are itemizing, including mortgage interest and property taxes.
