An 87 year old client's 2021 return is automatically generating Form 8801 with a carryforward from 2020.

This client has not paid AMT ever since I've had him as a client (2004). I've tried to remove this form, but it just pops up again.  He will never be able to use this carryforward, and since the 8801 form isn't final yet, I can't efile his Fed return either.

How can I eliminate this form?
