If you did not use a mailing service with tracking that confirmed for you that the envelope got there then you do not know if your envelope is in a pile somewhere----until something shows up in the system.
If you are wondering if you should send your return again——the IRS does not want you to file a second time. Putting two tax returns into the system at the same time can lead to confusion and even more delays. If you did not use tracking and do not know if the return was received—-you have to make your own judgement call and decide if you want to risk further delay by sending the return again. That is up to you.
