Yes, I know snail mail and all the associated delays / uncertainty is an option (see my previous reply). Thanks, but that is definitely not an answer to the original question. Maybe that is your way of indirectly saying "No I am not aware of any other method to use an e-file vendor to e-file an amendment". If so, thanks for taking time to respond. If I learn any new information for this tax year, I'll update here. Maybe some day, support for filing amendments will improve.
