Even if you start your 2024 return by "importing" a 2023 return, you always have the option of correcting or updating any incorrect information. You basically have 3 options.
1. Do nothing now, and after starting your 2024 return, correct anything that needs to be corrected.
2. Do nothing now, and start your 2024 return as a "new" return, not an import (start from scratch). You can manually enter any information that needs to be carried over. (How complicated this would be would depend on your other tax situations, such as business or rental depreciation schedules that need to be maintained.)
3. Prepare a 2023 amended return to reflect the changes. Mark the return as "filed" by saying you will print and mail it. Don't e-file. Then start your 2024 return by importing the amended 2023 return. However, you should still double check everything.
If you have been using Turbotax online, you may want to switch to the desktop program installed on your own Mac or PC from a CD or download. That will give you direct access to view the forms and verify all your information is correct before trying to file.
