Sorry----the IRS is severely backlogged. It is taking the IRS six to nine months to process mailed returns. So you still have to wait patiently.
TurboTax will not know anything about your mailed return, and will continue to show “Ready to Mail” on your account. TurboTax will not know that you put your tax return in an envelope and took it to a mailbox. TurboTax does not get updates on mailed (or e-filed) returns.
When the IRS opens its mail and begins to process mailed returns you can check the status on the IRS site. https://www.irs.gov/refunds
State returns have to be mailed to the state.

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 judgment call and decide if you want to risk further delay by sending the return again.
