Greatly appreciated Ms. T. Pandhare at E-Help office in MA. for her profound knowledge about how to apply for EFIN and very patient and kind professional assistance. It was the first time and only time in years that I received answers to my questions via phone calls to IRS. The rest just told me: “Call again in 30 days to check it out.” That is what I received after holding for 30 to 60 minutes. It has been going on and on for almost 3 years since it started, unfortunately, the refund of 2020 is not received yet. Anyone can help?
