After you file

first make a copy of your originally filed return or turbotax will overwrite it.

Then you can use TurboTax to amend and e-File a corrected return.

In Explanation you can say why Form 5329 and Form 8606 have dropped off your tax return. (i.e. no contribution)

The penalty on Form 5329 will be returned to you.

You should make sure your social security Line 6 is correct.

 

e-File of Form 1040-X makes your life much simpler.

The fact that you never made the IRA deposit certainly helps.
