Why backdoor IRA amend filing says due to pay more?

[gyongsu]

I already filed my 2020 tax report. 

After that, I learned the backdoor IRA which is converted from traditional IRA to Roth IRA with my post-tax money. 

In March, I contributed $6,000 to traditional IRA as 2020's and converted all of them to Roth. 

And also I contributed another $6,000 to traditional IRA as 2021's contribution and converted all of them to Roth again. 

Because I made my new tranditioanl and Roth IRA accounts after passing the calendar date for 1099-R, I couldn't get the 1099-R from TD Ameritrade. 

I followed the steps to enter manually for the amended report in Turbo Tax with only 2020's traditional IRA and Roth IRA.

In 1099-R inputs, I put the Box1 Gross distribution $6,000 and put the $6,000 to Bax2a as the taxable amount by checking Box2b as Taxable amount not determined box is checked.  With these inputs, the fed and state tax dues were estimated plus the amount. 

If I remove Box2a to $0 by changing Box2b unboxed, it can't be filed. The review message before sumbit, Turbotax screening told that box2a can't be zero. 

How can I submit the amended 1099-R for backdoor IRA which I made in March 2020?

And, should I make 8606 manually to send it separetely?

Thanks advance.

Thanks for your answers. 

Now I searched 8606 and entered the contents about the traditional IRS contribution, $6,000 for year 2020.

When I asked to the TD about the backdoor conversion, I got the answer, "A roth conversion is only valid for the year that is currently going on. For example if you want to do a roth conversion in 2021 it is due by December 31st of 2021. So a roth conversion for 2020 was due on December 31, 2020. We are unable to back date any roth conversions. " and no 1099-R got from TD Ameritrade. 

Does this mean I need not enter 1099-R for 2020? Can the conversion $6,000 for 2020 and $6,000 for 2021 processed to Roth in March 2021 be reported to the 2021 tax report?

To clarify, did you convert the traditional IRA to Roth only in 2021?

If yes, then your will get the 2021 1099-R in 2022 for $12,000  (2020 and 2021 contribution) and it will only go on your 2021 tax return. You do not enter the 1099-R entry on your 2020 tax return.

On your 2021 return to enter the nondeductible contribution:

1. Login to your TurboTax Account 
2. Click on "Search" on the top right and type “IRA contributions”
3. Click on “Jump to IRA contributions"
4. Select “traditional IRA”
5. Answer “No” to “Is This a Repayment of a Retirement Distribution?”
6. Enter the amount you contributed
7. Answer “No” to the recharacterized question on the “Did You Change Your Mind?” screen
8. Answer the next questions until you get to “Any Nondeductible Contributions to Your IRA?” and select “Yes” since you had a nondeductible contributions before this tax year.
9. Enter the $6,000 from your 2020 contribution (if that was your only basis)
10. On the “Choose Not to Deduct IRA Contributions” screen choose “Yes, make part of my IRA contribution nondeductible” and enter the amount $6,000.

To enter the 1099-R distribution/conversion on your 2021 tax return: 

1. Login to your TurboTax Account 
2. Click on "Search" on the top right and type “1099-R”
3. Click on “Jump to 1099-R”

Yes, I made both accounts and converted in March 2021 for all 2020's $6,000 and 2021's contribution $6,000.

Without 1099R, I will submit the amended report with only 8606.

Your anser is really helpful to me. Thanks.
