Capital Gain Tax on Primary Residence

I am 82 years old and my wife passed away in 2020 so I sold our home this year for $385,000.  We bought it in 1998 for $98,200.  Do I have to pay capital gain tax on any profit over $250,000?  I have always used the free version of Turbo Tax.  Will I be able to use this version to do this years taxes since I have to include this?  Also, I have moved in with my son and am wondering if there is any tax benefit for him since I am living in their house.  Thank you for your help.
