Retirement tax questions

Bogo, the financebuff link above has been updated for 2018. Quite a helpful walkthrough.

TurboTaxAnnetteB, I've followed these steps to a T for both myself and my wife but my 1040 preview is still showing my full contribution/conversion as taxable. I tried and re-tried this and can't seem to get that taxable line to zero out. Anything else I should try? Thank you.
