Oregon Paid Leave

What is the best practice for entering and calculating mandatory state paid leave in a retroactive account. Long story short, because we are so small, we assumed we were exempt. Now that we know we are not, we have calculated what that leave should have been for the 11 weeks missed. We are wanting to set up a line item to show that what we need to pull per employee for those 11 weeks now that we have it running appropriately for the weekly pull.
