Retirement tax questions

I am in a similar situation this year, My 401K is getting into excess that $19500 when combined with the three 401 K plans I have. If I request for removal of excess contribution form now with one of the 401K Plan admins (S corp), I am hoping I will get the 1099-R for 2021 FY since the money will be given to me by the plan admin in 2021. Is that the best way to handle this or should I go back and amend a payroll in which that 401K contribution was done? I don't want to complicate things like 2019.

Any input will be highly appreciated.

 

Thanks

Kevin
