If you are using TurboTax Online, You have to complete one of the spouse return (e.g. your father) and then when everything is completed, you click on 2024 Tax return (left menu), select the other spouse name (e.g. your mother) at the top of the page and you start entering the info.
We do not have an issue like this reported, at the moment. If the issue persist, let us know and we will have a closer look at it.
