My return was accepted on 3/14 and I never got it. Anyone know why?

 Around the second week of March most departments at the IRS either closed completely or began operating with very limited staffing.  As a result, the processing of tax returns has been significantly impacted and taxpayers who filed within the weeks leading up to that time period and since then are experiencing lengthy delays in many cases.

Tax returns filed by mail have not yet been scanned into tracking systems as they were simply placed in secure storage awaiting the return of operations.

Around the second week of June some IRS workers began to return to work and some limited processing of returns and other services have resumed.  It is not yet known how long it  may take for taxpayers to see updates to the status of their returns.

If you are still awaiting your economic impact payment ("stimulus check") you can check the status of that here: IRS Get my Payment Tool.

A delay in the processing of your tax return can also delay the processing of your economic impact payment.  The IRS will continue to process those throughout the balance of the year, but any taxpayer who does not receive theirs or whose payment is not for the proper amount will have the opportunity to file for their payment with their 2020 tax return when they file in 2021.
