Thanks for reaching out to us about payroll accounting preferences. I can share some insights about the After the fact feature.
When accessing or using the After the Fact payroll, QuickBooks automatically pre-fill the fields based on the payroll items and its setup rate. This is to avoid payroll calculation errors. Currently, there isn't an option for it not to pre-fill.
Let me know if there's anything else you need about After the Fact feature. I'm still here to provide more help. Have a good one.
