Thanks for the reply. Then I think my 8606 will be simple to just add up all of the contributions I made from 2018, 18, and 19? Since I haven't done and Roth Conversion yet.
Now that you mentioned about 1099-R. In 2020, I started doing 401K In-plan Roth Conversion which as you said I see that in Box 5 I have the after-tax money I contributed. Do I need to report 8606 for 2020 as well? This is still in my 401k plan.
