How to get all null items greater than 4 months from current

Question

I am trying to get all null items for a table column greater than 4 months from today's date using Linq. Below is my query. Although there are items, my query returns 0. I am not sure what I am doing wrong.

 

var FinalizedDate = DateTime.Now.AddMonths(- 4);

var test = EmpTable.Include(x => x.admintable.registers.Select(wt => wt.adminSurnames))

.Where(x => x.admintable.Id == 45

&& x.FinalizedDateTime == null && x.FinalizedDateTime > FinalizedDate).ToList();
