I made an excess contribution to ROTH IRA in 2015 . In April of 2016 I withdrew the excess of $2420. I received 1099 in 2016 for the distribution. I did not file form 5329 for 2015 or subsequent years and have been assessed penalty each year. Do I correct this by filing 5329 with my 2020 return? Or do I go back and file amended 2015 and 5329? Do I also need to amend 2016 through 2019 returns also?
