Capital Gain taxs on house owned with my Mom for 2 years , Mom passed I became owner

My mom  in her last years was too old to care for herself so My wife and I moved in with her for close to 28 months before she passed . I owned the house with mom for two years  she added me to deed before  . I do own another house too. 

Mom pass away in November 2023.  I sold the house April 2024. and moved back to my other home .

Since I owned the home with my Mom jointly and became sol owner time of her death . Would Capital Gains tax apply fully to me?  I am 69 and my wife 68 we are both on social security only income. Also gave half of the sale of the home to my only brother since there was no Will.
