I received a 1099R in November of 2020 for excess contributions to 503b plan in 2017. I changed jobs in January 2018 and don't recall receiving the 1099R prior to that. I called the new keeper of the funds when I found out and received the amount of excess plus differential in December of 2020. How do I handle tax filing if no funds were received in 2017 but only the report of excess contributions. Do I need to file an amended 2017 return even though the funds were not distributed out of the plan until 12/20.
Thanks Susan H
