Solo 401k excess number reported for 2022 moving to 2023 amend return

When filing my 2022 return, used "maximize" option on Solo 401 k for 2022 and the amount applied by Turbotax exceeded the individual contributions across 401k accounts. All contributions were made in 1st week of April 2023. Amending the 2022 return to correct the Solo 401k contribution amount with the rest applied to 2023 (since contributions were done in April 2023). No 1099 R etc issued. Does a simple amend to correct the 2022 number (and paying the additional taxes) suffice. Or is there anything more involved?
