Once u submit the non filer form and its accepted by the irs you cannot change it or resubmit. My fiance and I filed on April 13 and haven't received it either bc he accidentally claimed me as dependent. The irs said they are working on a fix bc they hadn't put a protocol in place incase ppl made a mistake and they cannot manually fix it or pull it from their system. The only thing you can do as of now is to amend it they said as they are working on a fix and if they get a fix b4 hand they will fix it
