Amend Incorrect IRA Contributions for previous year
For my 2019 taxes, I tried using TurboTax for the first time. I incorrectly added data to the Traditional and Roth IRA Contributions section (I added the number that had already been accounted for in my W-2). When I was going to file my taxes, TurboTax told me I'd made an excess contribution (because I added data in the wrong place). I ended up manually filling out the tax form and submitting it to the IRS last year.
When I'm filling out my taxes for 2020, it's carrying over data from last year and showing that I contributed $6,351.00 to my IRA last year (the bad data) and it's saying I'll have to pay a penalty.
How do I fix the incorrect data from last year? I thought Amending my last year's return was in order to re-submit it to the IRS, but there's nothing wrong with what I submitted last year, the bad data only exists inside the TurboTax software/website.
