Removing the mega back door funds that I contributed before the end of the year (December 2021)

I went ahead and contributed to my non-prototype after-tax account for the year 2022 even before the year ended in December 2021. I also went ahead and rolled-over the entire amount to to Roth also in December 2021. I know now that you cannot contribute to subsequent years and that I need to remove the excess. I have initiate the process for the removal from my custodian as it is a failed conversion. 

 

My questions:

 

1.  How many 1099-Rs should I expect and how will they be coded?

 

2. Do I need to file an amended tax return (1040x) this year to report the excess and the removal? if so, any guidance is appreciated.

 

Thanks.
