You can use TurboTax to amend your Massachusetts tax returns. You can only acquire TurboTax products from Intuit going back to the 2020 tax year. If you have TurboTax programs from previous years on your computer, you may be able to use them to amend tax years previous to 2020. Also, you can only amend a return to receive a refund going back three years from the due date of the return. You can mail all of the amended returns in one envelope.
