Please clarify if you are speaking of RRSP contributions or something else? If you are speaking of RRSPs, all contributions of January and February (first 60 days of 2023) are to be entered on the 2022 return. If you have overcontributed, please see our TurboTax articles: RRSPs and Your Tax Return: The Bottom Line 

How to Resolve RRSP Over-Contributions
