1099-S for inherited property - home

I received a 1099-S for sale of the home I inherited from my Mom.  I am using 2024 Home and Business Desktop.  When I enter the information, it says 1099B in the investment sales listings.  Is that correct?  Also, I paid various selling expenses for this transaction like Transfer Tax/Deeds filing etc., but when I enter those in on the box that asks that question, it does not adjust the sale for those expenses.  Do I add those expenses to my FMV at date of death?
