Skipping AutoFilter If Condition Is False

I am trying to write a macro for an autofilter which is triggered if an optionbox or checkbox is selected, i.e. Value=True. What is happening is that when the either box is selected it filters fine, but when it is unselected, the data is still being filtered using the previous results. My question is how do I write a macro that will skip a filter macro if the value=false. For instance, can I write an if then statement which will either skip the macro all together, or filter the data in that particular column as (All)?

Here is what I am working with so far, but it's not working.

Private Sub optlc_Click()
If optlc.Value = True Then
Worksheets("Sheet2").Range("B1").AutoFilter _
Field:=2, _
Criteria1:="y"
