amend sc return for unemployment exclusion

[rsnell5078]

I need to file about 8 amended SC returns and the DOR wants them efiled.  When I do the calculations and try to efile, proseries says the return has already been filed and does not seem to recognize this is an amendment.  Is  there somewhere else I tell it besides the checkbox on the information sheet?

I dont see SC in the list of states that can Efile an amended return. There at least one in the list that still hasnt been enabled as well, but SC isn't even a future option.
