Retirement tax questions

@DanaB27 The exact situation is this:

 

Age is over 59 1/2 and the Roth IRA was opened back in 2007.

 

In 2021, incorrectly contributed the max allowed for 2020.

In 2021, incorrectly contributed the max allowed for 2021.

In 2022, incorrectly contributed the max allowed for 2022.

In 2023, incorrectly contributed the max allowed for 2023.

 

In March 2023, the broker removed all the excess contributions in 4 separate transactions. For years 2020 and 2021, they took the exact amount out that went in ($7K went in, $7K came out). For 2022 and 2023, they did calculate earnings and took out more than the original contributions, so there are earnings to report for those years.

 

The broker indicates that the 1099-R forms will be coming at the end of the year. No taxes were withheld.

 

At this point the goal is to figure out how and when to file the 2020, 2021, and 2022 returns, and whether to file an amended 2022 return next year when the 1099s are in hand, or guess at the 1099-R codes now. If we wait for the 1099-Rs, would all 4 of them be reported on the 2022 return, i.e. in 2024 is that the only return that would need to be amended once 1099-Rs are available?
