The letter from the IRS will have instructions on what you need to do.  What does it say?

Did you get a letter telling you the IRS needs additional time to process your return because they are waiting for your tax file to show up on their computer? If so, it’s a generic letter millions  of people are receiving from IRS to buy them some time to process the returns.
