Nothing has changed. TurboTax continues to treat income from a nonqualified deferred compensation plan present on Schedule 1 line 8t as income that does not support an IRA contribution.
If TurboTax is allowing you enter an IRA contribution without treating it as an excess contribution, TurboTax must be seeing some source of compensation that does support the contribution. If so, if you are married filing jointly, that source could be your spouse's compensation.
