I just extended the formula for each month so I don't have to do an greater than/less than statement. the formula below worked from me :)
If(
Month([Est.Project End Date])=1,"Q1",
Month([Est.Project End Date])=2,"Q1",
Month([Est.Project End Date])=3,"Q1",
Month([Est.Project End Date])=4,"Q2",
Month([Est.Project End Date])=5,"Q2",
Month([Est.Project End Date])=6,"Q2",
Month([Est.Project End Date])=7,"Q3",
Month([Est.Project End Date])=8,"Q3",
Month([Est.Project End Date])=9,"Q3",
Month([Est.Project End Date])=10,"Q4",
Month([Est.Project End Date])=11,"Q4",
Month([Est.Project End Date])=12,"Q4",
"")
