I want to claim RRSPs for whole year 2023, it is clear how to enter March to December, how to enter the amount for 1st 60 days of 2023 ?

I don't want to claim the first 60 days of 2024 in my 2023 tax return

Contributions made in the first 60 days of 2024 are for tax year 2023, so yes, you would need to enter them on your 2023 return. You don't need to take the deduction in 2023 though.
