Retirement tax questions

I do not have any non-deductible left in traditional IRA since 2019. In 2019, I converted everything to Roth IRA. Since then (2020, 2021) I always contribute to IRA first with my after tax money and convert full amount to Roth IRA right away. So my traditional IRA balance is always 0 at the end of the year. Hope that helps.

 

When you say "your basis should be used up", does that mean that my basis should be 0? But it was not showing 0 on my last year 8606- not sure why?

 

Also, is it that I need to keep reporting my contribution to IRA (even if I converted all of them to Roth later) on 8606? Thank you!
