How do you undo (delete from input) an amended return form and return to the original tax return letter and information? i.e - how do you delete a 1040X within the data entry? Client had interchanged 2 childrens' SS in 2 previous tax years. We started to set up an amend and decided to hand write rather than amend those past years. This is first year working with this client and 2019 SS numbers for these children will now be reported differently. Lacerte keeps referring to a 1040X that we cannot seem to delete and complete only current year tax return.
