To amend your return, you need to wait until the IRS processes your original return. If it is rejected, you can make the necessary changes to your original return and resubmit it with no need to prepare an amended return.
If it is accepted, you need to wait until the IRS processes it and sends your refund if you are getting one. You can then begin the amending process. Do not change your original return until you start the amended form 1040X. It will not be available in Turbotax until February. The amended return must be prepared, printed, signed and mailed by you. It can't be efiled. It takes the IRS about 16 weeks to process an amended return.
