TurboTax is probably working as designed. The amounts from Box 145 often end up on the other spouse's return
From the CRA site regarding Social Assistance payments:
"However if you lived with your spouse or common-law partner when the
payments were received, the one of you who has the higher net income on Line 236 – Net income (not including these payments or the deductions on Line 214 – Child care expenses or Line 235 – Social benefits repayment) has to report all of the payments, no matter whose name is on the slip."
