@minabian  You can amend a tax return that you prepared elsewhere using TurboTax, but it will be a real pain.  If you can go back to wherever you prepared your original return you would have an easier chore.  In order to use TurboTax you first have to purchase the desktop software and install/download it to your computer (not a mobile device).  Then you have to re-create that original return EXACTLY as it was when originally filed.  You then tell the software you are going to file by mail so the software “thinks” you filed the return.   After that, you go to the section to “Amend” the return  (It is under Other Tax Situations>Other Tax Forms>Amend a Return).  Then you amend the return to prepare a Form 1040X, which will have to be printed, signed and mailed.  Amended tax returns cannot be e-filed.

Wait about 3 weeks and you can check the status of your amended return:

It will take about 3-4 months for the IRS to process an amended return.

Yes, you can use TurboTax to prepare your amendment, even if you did not file using the software.

You can find TurboTax software from previous years (you will need the 2014 software to amend your return) at https://turbotax.intuit.com/personal-taxes/past-years-products/.    

Instructions on how to prepare the amended return can be found below.  After you click on the year you want to amend, you should select the option to amend using CD/downloaded software.

Please note that these instructions assume that you prepared your return using TurboTax.  Since you did not, you will want to enter the information from your return as originally filed, then proceed starting in Step 3.

When you have prepared your amended return and are ready to mail Form 1040-X you should include the following forms:

• The new (amended) Form 1040
• Any forms or schedules that were added or changed as a result of preparing the amendment

Please note that 1040-X cannot be e-filed - you will need to mail a paper return.  It takes the IRS at least 2 - 3 months (and sometime up to 6 months) to process amended returns.  Also, depending on whether the changes affect your numbers, you may also be required to file an amended return with your state.  

The mailing address for you state and situation can be found at https://www.irs.gov/pub/irs-pdf/i1040x.pdf.  Look under Where to File on page 14.
