Retirement tax questions

Thank you for the detailed, step-by-step instructions.

Your assumption is correct - no traditional IRA distributions in 2017 or 2018.

I performed  steps 1 through 7 as you described, and the taxable amount of my 2019 distribution was reduced by the full amount of the amount shown in box 5 of the 2017 1099-R. This is what I had hoped for, but is that what is expected? I'm concerned that on form 8606-T, line six (value of all IRAs as of 12/31/1019) is blank. HAve I overlooked something?
