RRSP Slip for first 60 days claimed in prior tax year causing mismatch for retirement severance transfer, as noted in box 66 of T4.

Retirement Severance rolled into RRSP by employer first 60 days of 2022, claimed on 2021 tax year causing mismatch with 2022 T4 and box 66. Entering transfer in RRSP section does not reflect dollars as non-taxable. Does anyone know of a solution?
