You can find a past contribution job and download just its failed records from your Submit Contributions history.
To do this:
Go to Submit Contributions › History
Use the Status filter on the right and select Completed With Errors
Select the contribution job for the period you need
In the Uploaded File section, select Download Failed Records Only
Make your fixes to that file, then upload the saved CSV as a new contribution job.
As best practice, update your payroll software with the correct data so the same error does not recur.
