The program can be used to complete an amended Virginia return but you will not be able to use the state interview step by step to make the changes. All changes will need to be made directly to the forms.
Please see the screenshot below (which is shown in the TurboTax program when you state you want to amend the state return) and follow the instructions to complete the VA amended S-corp return. We highly suggest saving the original file, and creating a copy for the amended return. This will ensure you have all of the original forms in case you ever need them to refer back to.
