Reporting Roth IRA re-characterization and backdoor conversion?

[victors9739]

My spouse and I both made maximum contributions for both 2018 ($5500) and 2019 ($6000) before April 15, 2019. Upon filing 2018 taxes in TurboTax, I realized we were ineligible for Roth contributions due to household income.

I immediately re-characterized both the 2018 and 2019 contributions (from Roth to Traditional) in March 2019 before filing for 2018. I filed my 2018 tax return with an explanation statement for the re-characterization of the 2018 contribution (basis + earnings).

In late 2019, I learned about backdoor Roth conversions and handled that for the full balance of my traditional IRA (after consolidating all other Traditional/SEP/SIMPLE accounts). Following the backdoor conversion, Vanguard sent me Forms 1099-R for the traditional and Roth IRAs. I've entered these as part of my TurboTax filing for 2019.

At this point, it seems that I'll need to amend my 2018 return to cover the backdoor conversion for the 2018 basis (since there are taxable earnings because I waited a few months between re-characterization and backdoor conversion). For 2019: as long as I've entered all the 1099-R information as received, and have entered the re-characterization information via "Traditional and Roth IRA Contributions", do I have any other reporting responsibility here? I know I'm covering the re-characterization through TurboTax's prompts; I just want to be sure I'm covering the backdoor conversion by merely entering the 1099-R info.

Thanks!

If you recharactorized it all and indicated that the recharactorized Traditional IRA contribution was to be non-deductible and that was on your 2018 tax return, the there should be 8606 forms with the non-deductible amount on lines 1,3 and 14.

Why do you think you need to amend 2018?

You would enter the 2019 1099-R for the conversion and enter the past years basis (line 14 from the 2018 8606) and the 2019 year end aggregate value of all IRA accounts and the taxable amount will be calculated on a new 8606 lines 6-18.
