Do I have to file 1040X to update the non-deductible IRS contribution?

Thank you! Do you mean I just leave entire column A, B, C blank? So, I only need to fill out personal information section and the "explanation of changes" section?

If you aren't changing any dollar amounts, skip lines 1-23 and proceed to Part I.

In your case you would skip to Part III.

Basically you are using the 1040X as a cover sheet for the form 8606 you are attaching since the IRS seems to want one.
