I filed my 2019 1040 in mid March 2020 At the end of March I decided to do a back door Roth for both 2019 and 2020. My 1099-R correctly states that my gross distribution is $14,000. I don't know how to fill in form 8606 to indicate that $7,000 was contributed to a traditional IRA and then converted to a Roth (for 2019) and $7,000 was contributed to a traditional IRA and then converted to a Roth (for 2020).
