manually, any idea to what, and how about vendor records/trans.

thks made change

1099/CPRS codes no longer correspond to specific box numbers on forms, because these box numbers may change from year to year (which has happened with several boxes in tax year 2020, including the change to Nonemployee Compensation discussed above).

Instead of using the code as an indication of the box number where amounts should be reported, for each code you now specify a type of payment (or other amount) to be reported on 1099/CPRS forms. When you print a form for a specific tax year, amounts are automatically printed in the correct boxes for that year.

To continue using your existing 1099/CPRS codes, update each of them by specifying a tax reporting type (1099 or CPRS) and an amount type. Also, consider creating 1099/CPRS codes with meaningful names for your next reporting cycle (for example, if you currently use code 7 for Nonemployee Compensation, you might replace this code with one named NEC). If you create new codes, ensure that you assign them to vendors in Accounts Payable.
