OK, I'm getting scared now as I have multiple entities to file tonight and tomorrow. I just completed an 1120S and ran Error Check. It's telling me there are 80 errors in my return. When I click on specific errors it brings up a page in another client's return. Not just one other client but different clients for different errors. The return I'm working on is error free. I closed out and when I got back into the client it's not happening now but it has me a little worried about what will be efiled with this return tomorrow. Has anyone else seen this happen?
