In TurboTax, after you complete your Federal return, start your Vermont state return. Proceed through the program until you see the asking if you “rented” and follow the program prompts.
Refer to the TurboTax Vermont instructions included in your return on how to file.
So when you had the chance to review the return did you see that form ? If not click on the Print Center in the Tax Tools and save a PDF of the return and review the state filing instruction page.
