Mailed in Amended returns are currently taking 6 months or more to process AFTER your original return has been processed AND any further corrections the IRS was making automatically ( like for the unemployment exclusion) only then will they even look at your amended returns ... eventually once they open the amended return and enter it into the system for processing you will be able to track your return's progress here : https://www.irs.gov/filing/wheres-my-amended-return
