I put my name instead of my wifes name on the return. the one I completed was her's not mine. can I simply change the name on the return and send it on????

As long as you have not already submitted your return and it has not been accepted by the IRS then you can go back into TurboTax Online using the tabs near the top of your screen, Personal Info, Federal Taxes ,State Taxes, Review, File and make any changes you need to.To edit your personal information, go to the Personal Info tab. Please let me know if you have any problems.
