Backdoor Roth IRA contribution
In early 2020, I contributed the maximum amount for 2019 and 2020 to an IRA for both my spouse and I, and did a backdoor roth IRA with those funds.
After I finished inputting the 1099-R (which reflects the max amount for both 2019 and 2020) in my 2020 taxes, it says that I will incur a penalty because I exceeded the maximum amount I can contribute in 2020.
What is the proper way to handle the 2019 contribution? Do I need to amend my 2019 taxes? To make matters worse, I have hard copies of my tax returns for 2019, but my computer crashed and do not have access to the 2019 tax return file.
