1099-R for 2020 not generated until 2021

Hello,

 

In March of 2021, I removed an excess contribution and its earnings from my Roth IRA for 2020.

 

I am aware that the interest I just removed  is taxable in  2020, but the 1099-R will not be generated until 2021.  Can I report this amount on my 2020 return before receiving the 1099-R or must I wait until next year and file an ammended return?
