Unfortunately, this is not something that can be fixed in TurboTax. CRA does not allow many software versions, including TurboTax, to support the T2203 Form - Provincial and Territorial Taxes – Multiple Jurisdictions and NetFile.
They require that this form be attached to a paper filed return and mailed in. The form can be found here: T2203 Provincial and Territorial Taxes for 2019 - Multiple Jurisdictions
