@justine1195 , assuming that you have looked at 'Where is My Refund" page at www.irs.gov and have not had any joy, I suggest you make an appointment with the local IRS office ( hopefully you are not too far away from one of these ) and do a face-to-face with an agent/person. I know the IRS is way behind on many 2020 returns but efiled returns should have been settled sometime ago.
Is there more I can do for you ?
