The IRS is way behind in processing mailed in returns. An amended return can take 8 to 16 weeks to be processed. The IRS did not start processing mailed in returns until recently. Since the IRS has been behind since Covid, it is taking them longer to process mailed in returns. You can check the status of your Federal amended return at the following link:
