let's say it's not unusual. the IRS was hit hard by the pandemic and then the need to program its computers to issue the stimulus checks. for a couple of months, the IRS was not processing paper submissions. so now it has millions of paper returns, addendums, faxes, forms. responses to notices, etc to process. keep using the TT tool or IRS website to check status. there is nothing anyone can do especially if the IRS has not yet processed the paper submission.
