Can't he change his Roth contribution in Turbotax for the sake of recording his Roth IRA basis without amending his tax return since it is not affected? If yes, what is the process?
I think, with Turbotax Online, the only way to change the tax file is via the amending process. In this case, Turbotax will tell him there is nothing to amend, and you don't need to actually file an amended return, but the updated information will still be in the system. If you are using Turbotax on your own computer, you should be able to update the data file without amending.
Or, leave it alone, and update it next year when he files. He will again be asked if he wants turbotax to track his contributions and he can provided updated contributions then.
