It might be that box 13 on your W-2 form that says Retirement Plan is checked. By default, that would mean that you were covered by a retirement plan at work. It may be that you are overiding that when you answer the questions in the retirement plan contribution section in TurboTax, but it is reverting back to the default position when you log out of your program. Either way, if you review the copy of the return that you submitted and determine that it was correct as filed, you won't need to do anything further as far as filing your return is concerned.
The only way to determine for sure what return was e-filed is to request a transcript of your return from the IRS as follows:
