Have you filed your taxes yet?
If you have already filed, you can return to the program to make corrections without amending only if your return is being rejected. If your return is accepted, to edit your tuition information, you will have to amend it. You can not return to the program to change.
If your return got rejected for any reason, you can return to the program/account to edit the tuition information along with other changes and re-submit it. For instructions, click here Fix a reject 2019. You do not need to file an amendment 1040-X.
