Unemployment change now allows EIC for clients. Locked returns for clients who had already filed before unemployment tax law change. Question is when I go to amend the return, when unlocking the file new information immediately flows to the return. When preparing the 1040X the correct info will need to be entered manually?  Or is there a way to stop corrections when opening the file. I do have paper backups for these files but of course the first one I look at will have to be amended.
