@faisalels-hotmai The IRS is woefully backlogged. Since you paper filed, assume it will be 6-9 months from the time you mailed the return until the return is processed. You will not be able to see anything on the WMR tool until they begin processing the return. (you state 'emailed certfiied mail, but that sounds like a paper file).. Only thing you can do is show patience - here is what the IRS ebsite states:
How long you may have to wait: The IRS understands the importance of timely processing of tax returns and refund issuance. We have processed all error free returns received prior to January 2022 and continue to work the returns that need to be manually reviewed due to errors. We are continuing to reroute tax returns and taxpayer correspondence from locations that are behind to locations where more staff is available, and we are taking other actions to minimize any delays. Tax returns are opened and processed in the order received. As the return is processed, whether it was filed electronically or on paper, it may be delayed because it has a mistake including errors concerning the Recovery Rebate Credit and the Child Tax Credit, is missing information, or there is suspected identity theft or fraud. If we can fix it without contacting you, we will. If we need more information or need you to verify that it was you who sent the tax return, we will write you a letter. The resolution of these issues could take 90 to 120 days depending on how quickly and accurately you respond, and the ability of IRS staff trained and working under social distancing requirements to complete the processing of your return.
What you should do: In most instances, no further action is needed but you may check Where’s My Refund? or you can view your account. If you filed electronically and received an acknowledgement, you do not need to take any further action other than promptly responding to any requests for information. If you filed on paper, check Where’s My Refund? If it tells you we have received your return or are processing or reviewing it, we are processing your return, but it may be under review. If you filed before January 2022 and Where’s My Refund? does not have any information, your return has been opened but work on it has not begun. We’re working hard to get through the carryover inventory. Please don’t file a second tax return or contact the IRS about the status of your return.
@faisalels-hotmai - the IRS processes the returns generally in the order received. Users postings on Facebook groups are stating they mailed in their returns in Feb and just now getting their refunds, so that is a 6 months delay right there. So best to assume 6-9 months. More than 9 months, while possible, isn't likely.
