Can I use TurboTax to send an amended return if I already sent in a return from another preparer?

I used Credit Karma to send in my original federal and state (CA) returns but need to amend to include sale of my home residence.

Yes, you can use TurboTax to complete an amended return even though the original return was not done with TurboTax.

To this, you must replicate the original return. Meaning you will create an account with TurboTax and compete the return exactly as you did with the original return. You will follow the onscreen guide to complete the return, once you get to the File section, you will select "File by Mail" follow the on screen guide to print the return (you will not actually file this return, you are doing this in order to get the original return into TurboTax). 

Once you have completed replication the original return, you will then follow these  instructions to amend the return.

We do recommend that if you are expecting a refund, please wait until you have received the refund before completing the amended process. Reason being, it can take up to 16 weeks for the IRS to process and amended return. 

Keep in mind that you cannot e-file the 1040-X Amended Return. All amended returns must be filed by mail. Mailing instructions will be provided by TurboTax once you have completed the amended return.
