I am trying to e-file a 2021 amended state return, but when I try to access the return on my computer, it says the file is locked, but it says it is locked by the computer I am currently using, so I should be able to access the file. I tried updating, refreshing updates, etc. Nothing is working, no one has locked the file or has the file open, so if someone could help me figure this out that would be great. I need to file this return before the deadline.
