In T+1, what is the final time I can do the EDIS. Is it 3pm or that entire day?

Just reazlied after my broker’s email that EDIS didn’t went through, so submitted it about an hour after 3 pm when nepse close, Will they charge 20% or will it count T+1 still. I sold them yesterday, so today all day should be technically T+1 right?
