Mailing in taxes canceling e-file

The software program does not know you put your return in an envelope and took it to a mailbox.   Your account will always say "ready to mail" or "printed" even if you mailed the return.   Once you mail it, you have to wait to see information on the IRS refund site.  

TurboTax does not get updates on mailed  (or e-filed) returns.

If  you mail a tax return (or a payment) to the IRS, it is a good idea to use a mailing service that will track it like UPS or certified mail so you will know it was received.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. 

Mailed returns take a long time to be processed---it may be months before the IRS processes a mailed return.

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