Why won't CRA accept my spouse's return on netfile ? Keeps giving #90121, NA, NA response even though my netfile worked.

[TurboTaxTara]

According to CRA's NETFILE error guide, #90121 is related to the amount on line 121: interest and other investment income amounts.

Double-check any entries made in your spouse's return for T5 slips, T3 slips and T5013 slips.
