Can someone please help me? I screwed up on my federal tax return because I added my 401(k) contributions twice: once where they belong and once in the IRA slot.

I only realized after I e-filed, so I need to amend or cancel it somehow.

If your return is accepted you will get an email. If the return is rejected the e-mail will tell you what to correct and you can make changes before e-filing again. Amend to change an accepted return. Instructions below. https://ttlc.intuit.com/community/amending/help/how-to-amend-change-or-correct-a-return-you-already-...

Once you transmit your return there is nothing else you can do but wait. If your return happens to be rejected for some technical issue, you can correct the IRA problem as well as the technical issue. If your return is accepted, you will have to file an amended return, which you should wait to do until your original return is fully processed and any refund paid.
