Hi, I filed my federal return by mail in Oct. 2021 under tax extension, and after 3 months later I haven't received my refund. Then, I checked my refund status in IRS website by clicking the blue " Check My Refund Status" button and input my information, but the website tells me ""We cannot provide any information about your refund " I tried a few times and I am sure I input correct information, but got the same results. The search results tells me that it looks like the IRS system doesn't have my tax return information. I am starting to worried about my return. Where is my return? To make sure my return sent to IRS safely on the way, I did mail my return in certified mail and I even spent extra dollars to request a returning receipt to be signed and returned back to me. My return was delivered successfully by UPS and the returning receipt stamped by IRS was returned to me. This means IRS did receive my return. But now the IRS refund search result tells me no information of my return was found. I understand because of Covi19 pandemic, the processing time will be longer. The issue now looks like my return is not even in IRS system! Where is my return?! Where is my refund? I called IRS refund line but it is a automated phone line, and I got the same results as the one by searching IRS online. What should I do now? I really appreciate your help. Thank you so much.
