Thanks for your reply. I made the contribution for 2018 in 2019 (between Jan-Apr) so I didn't have a 1099-R until I got the 2019 one for both. So would I still need to file an amended return for 2018? My understanding was that you can make an IRA contribution for the previous year up until the tax deadline of the following year.
I understand that I need to file an amended return and Form 8606 for 2019. Just wondering if I need to do the same for 2018.
