IRS asking for completed 5329 for amended return but 5329 wouldn't be there in the first place, what do I need to submit?

I have made a mistake last year and reported my HSA contributions twice - form 5329, line 47 and 48 filed as excess contributions (the contributions counted twice). Submitted 1040X and now IRS is asking me to submit a completed 5329 which wouldn't be there in the first place. Should I just sign a form with nothing on it or specify 0 on lines 47 and 48 - not sure what to do here... Thanks for the help in advance!
