How to implement repository in clean architecture

Question

I need to rewrite my project due to many underlying issues causing errors and I started following clean architecture by Uncle Bob (I read the book).

I created my domain, infrastructure, application and interface-adapters. In my domain directory I have an entity called TreatmentPlan containing all the business logic. I also define ITreatmentPlanRepository which defines my base methods of accessing data.

This is my TreatmentPlan entity

// TreatmentPlan.ts
interface TreatmentPlan {
    id?: number
    physicianId: number
    patientId: number
    startDate: Date | string
    endDate: Date | string
    endReason: string
    status: TreatmentPlanStatus
    diagnosisId: number
    diagnosisDate: Date | string
    initiationFormId: number
    activeSubstanceId: number
    activeSubstanceDosageId: number
    countryId: number
}
// TreatmentPlanRepository.ts
import { TreatmentPlan } from './entities/treatment-plan'
export interface AbstractTreatmentPlanRepository {
  listTreatmentPlans(): Promise<TreatmentPlan[] | []>
getTreatmentPlan(id: string): Promise<TreatmentPlan[] | null>
createTreatmentPlan(data: any): Promise<TreatmentPlan>
updateTreatmentPlan(id: string, item: any): Promise<number>
deleteTreatmentPlan(id: string, force?: boolean): Promise<number>
}

In my application directory I define my usecases eg. CreateNewTreatmentPlanUseCase. I know I want to use Sequelize ORM for database. I inject AbstractTreatmentPlanRepository to CreateNewTreatmentPlanUseCase.

In my infrastructure I have sequelize directory defining all the models and connection.

But I cannot figure out which layer I need to create my SequelizeTreatmentPlanRepository. Some say it needs to be in the interface adapters and some say it needs to be in the application layer. I would put that into the infrastructure directory but I cannot import anything from domain since this is the most inner layer of the structure.

Any help would be appreciated.
