Get your taxes done using TurboTax

You may have misread what the program told you about mailing your return.  When you report investment sales using summary totals and e-file your return, you have to either attach a copy or mail Form 8453 and your Form 1099-B (or other transaction detail) to the IRS if either of the following is true:

 

  • You made adjustments to your investment income.
  • Your cost basis isn’t reported to the IRS.

If using TurboTax Online, you have the option to upload/attach a copy of Form 8453 and your 1099-B or mail them.  If using TurboTax Desktop you have to mail them.

 

You do not have to file your return by mail.  You do not have to mail a copy of Form 8453 and your 1099-B to the state.  If you import all of your transactions and e-file you will not have to mail anything.   

 

Intuit does not store/retain or do anything else with the password to your Financial Institution.  Form more information, see the following TurboTax Help Article:  

 

When do I need to include my 1099-B with my return?
