I had to make changes to past taxes, & got revised NOAs.How do I change the records in previous years copies of Turbotax so that the changes are recognized by Turbotax24

For example for Turbotax to show correct history in reports and to correctly calculate available RRSP room and CNIL. And if i have two versions of a .tt22 file for example, which does Turbotax choose for previous year's data?
