How to Report Backdoor Roth IRA for 2019 in 2020?

Hi,

 

In 2017 I did a backdoor Roth IRA (contributed $5500 to traditional in 2017 and converted to Roth in 2017) and followed these instructions which were great:

In 2018 I did not make an IRA contribution and therefore did not get a 1099R or fill out form 8606.

 

In 2019, I contributed $5500 to traditional for 2018 and converted to Roth a few days later in 2019. Now I'm not sure how to report this in TurboTax?

 

For "Any Nondeductible Contributions to IRA?" am I supposed to say Yes?

 

In the Deductions & Credits Section of "Tell Us How Much You Contributed":

Total 2019 traditional IRA contributions: $5500

Tell us how much of the above total contribution for 2019 you contributed between 1/1/20-4/15/20: If I put $5500 my refund goes way down. If I put 0, that's what my refund is supposed to be.

 

Am I supposed to ammend my 2018 tax return with a form 8606?

 

I just did the same for 2019 (contributed $6,000 to traditional in 2020 for 2019 and converted to Roth in 2020). For 2020 I'd like get back on track and contribute $6,000 to traditional in 2020 and convert to Roth in 2020 to avoid this situation from now on.
