Here are the steps to remove the form (online):
If this does not work, you might have to remove the dependent completely and delete the form 2441 and related worksheets, then re-enter the dependent info.
I had the same issue helping a customer today. If you delete the child, it will remove the 2441 - then you can go back in and add the child back. It's much easier than going back and forth trying to get the 2441 to delete from the delete forms screen. Took 3 minutes and the return was ready to file.....no errors.
