I want to change from efile to mail in. I used the process you provide, many times. The option to change never appears. What to do?

You want to file by mail?   You can do that, but you have to pay your TurboTax fees first so that you can print your returns.

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.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.

 It is taking the very backlogged IRS six to nine months to process mailed returns.   Until a human opens your envelope and enters the data into the system, nothing will even show up on the refund site, so you will have to be very patient.
