I filled my five W-2’s with a CPA but one of the five is a Canadian based company and she said she wasn’t able to file it. How would I go about filing an tax addendum?

CAN I USE TURBOTAX TO AMEND IF THE RETURN WAS PREPARED SOMEWHERE ELSE?

Sounds like you need a better CPA.

If you did not use TurboTax to prepare your tax return, it is possible to amend the return using TurboTax but it will really be a pain.  It would be better to use the software or service used to file originally.  If a paid preparer made a mistake on your tax return, that tax preparer should do the amended return for you at no charge.

In order to use TurboTax to amend your return, you need to purchase the desktop software for the tax year and re-create the return EXACTLY as it appeared when it was filed with the IRS/states.  Every line has to be the same.  Then you have to "trick" the software into thinking you filed by saying you will mail the return. (but do not mail it)   AFTER that, you use the software to prepare a Form 1040X, which has to be printed, signed and mailed to the IRS.  It takes the IRS about 6 -9 months to process an amended return

Since you didn't file the original return with TurboTax, you would need to create an account.  Re-create the original return, then select print for mailing.  You would then go back and select Amend My Return and add in the income from the Canadian based company.

Are you sure she did not include the income somewhere else on the return?  A CPA should know they have to include income from any and all sources and should not file until they did include it all.
