You can log back into your account to make changes anytime prior to filing your return.  Click Tax Home in the left hand menu.  Click Federal (or State) and you can navigate through the different sections of your return using the top menu links (Personal, Deductions and Credits, etc).

If you have already e-filed (or mailed) your return, you will need to wait until your return is either accepted or rejected to make changes.

Form 1040 rejected with FDI_8615Line7Box_ErrorHold code after filing.

We followed the TurboTax email instruction to help fix it: they are useless, TurboTax simply said redo 1040, but does not let us to fix/edit the forms that we think TurboTax made errors.

Extremely frustrating and unprofessional for TurboTax.

Please contact phone support for further assistance with this error code.  Refer to the following TurboTax FAQ for the contact number:  What is the TurboTax phone number? - Community
