The issue is that your Original filed tax return amounts were not “frozen” before your amendment was started in TurboTax. Ideally, you would immediately start the Amend a Filed Return (button on lower left when you open your TurboTax Download/CD). If you opened the Original tax return before you started the Amend process, the software update was applied, and may have changed that tax return before you started the Amend process.
If you saved a copy of the Original “.tax2019” file, make another copy to make sure you have a “spare”. Then, start TurboTax, immediately click the Amend a Filed Return button on the lower left, and then choose a copy of the Original “.tax2019” file.
You may be able to “get back” to the Original filed return if you “undo” the amend process you’ve started. But, because the changes were made by a software update, that may not work. Similarly, you may or may not be able to “recreate” your original return in a TurboTax Download/CD version, but the software update may also make that difficult. It could be that whenever you open the “.tax2019” file for your original return, the calculations will update.
Another option, and it may be the least frustrating approach for you, is to use the amended TurboTax Form 1040 you now have (after the update) to include with your Form 1040X filing, but either in Forms mode “override” the Form 1040X Column A in TurboTax Download/CD or prepare a manual Form 1040X outside of TurboTax. When you are finished, Column A should “match” the Original return you filed. Column C should match the “amended” tax return you have in TurboTax. Column B should be the difference. Check to make sure lines 16-23 are correct for the 1040X you are filing.
The 1040X must be mailed, it cannot be e-filed. The “package” is the Form 1040X and the “new” Form 1040 with your amendment changes.
