Year End Deductions Due to CRA

I've been using Sage for years and at the end of the year there is usually a small discrepancy owing for this small business to CRA

But this year there is over $4200 owing  for EI and CPP

I don't know where this came from, I'm extremely stressed, its a bad year for them as it is for everyone since there under their 3rd lockdown.

I've had there accountant look at it too and they cant seem to find any issues

Did anyone else have any problems with 2020 employee deductions assessments

Please help ,
