because of Covid the IRS is behind in processing returns especially these mailed in, those where taxpayers filed a non-filer return to get the stimulus (but that return filing meant no other return for the year but IRS records show there's a tax return due) and maybe even e-filed returns. the IRS has your return and is processing the return (checking it) or it's in the queue for checking. eventually the IRS will get to it and if there are no issues with it, send out your refund. if there are issues the IRS will send out a notice asking for additional info. if you move make sure you update your mailing address with the USPS and also with the IRS by filing form 8822
