Do I understand correctly that to amend a 2017 TurboTax file, for example, you MUST use the 2017 TurboTax program, and you cannot use the 2018 or 2019 program? If I have the original installation file, is that enough to guarantee that it will re-install on a new computer? (I.e., Intuit doesn't assume that the file was pirated from someone else, etc., and prevent you from installing a second time on a new machine.)
Thanks for any response
