No, you should not re-mail in your amended returns. That could really delay your return. Amended returns take up to 16 weeks to process & longer since the IRS is backlogged. It can take up to three weeks from the date you mailed it to show up in our system. There's no need to call the IRS during that three-week period unless the tool specifically tells you to do so.
From the IRS:
We're open and processing mail, tax returns, payments, refunds and correspondence. However, COVID-19 continues to cause delays in some of our services. Our service delays include:
- Live phone support
- Processing tax returns filed on paper
- Answering mail from taxpayers
- Reviewing tax returns, even for returns filed electronically
