Yes. If you have the Desktop CD it has both the Windows and Mac programs on it. If you bought the Mac download you need to call in and ask for the Windows download. You can transfer from 2019 done on Mac into the Windows desktop program. You just need to copy your return file ending in .tax2019 to the Windows computer. If that doesn't cover what you need please post more details.
