It is better to start using VS2019. Even free of charge Community edition is good enough to develop SSIS projects. VS2019 is not using SSDT anymore. It needs "SQL Server Integration Services Projects" extension for VS2019. Here is its download link: https://marketplace.visualstudio.com/items?itemName=SSIS.SqlServerIntegrationServicesProjects
VS2019 supports all versions between 2012 - 2022. Please see below.
