Banking

Morning!
I have a part time employee that has been off work with covid last week so I went on the HMRC calculator last week to see how much they were entitled to.  They work 20 hours a week worked over 3 days.  HMRC calculator told me they were entitled to £96.35.  

However when I enter the details through QB it works out their SSP to be £55.06.  I understand if they were off with an sickness that was not Covid that they would get a different amount than they do because they had Covid.  

So, is there a different way of entering SSP for a covid sick period into QB.  

Thank you in advance :)
