Filter report by current month

Filter report by current month

I have a report with a dropdown month field.
I need to filter the report to only show records for the current month

I have tried:
Renewal_Month == zoho.currentdate.getMonth()
Renewal_Month == zoho.currentdate.toString("MMMM")

I also created a formula field that is input.Renewal_Month and tried both above option with the formula field.
None of them work.

How do I get this report to filter buy current month
