Let me help with your question about recording old paychecks, DesktopPayroll2021.
I can see that the Paycheck History page only list the taxes and payroll item that are paid by the employee. This is why you can't see the option to unemployment or company-paid taxes.
After recording the prior payroll data, QuickBooks will automatically add the unemployment taxes in the employee records. The amount is based on the taxable amount that you put in, multiplied by the tax rate that you provided for state unemployment. You will see it in the Year-To-Date Adjustments in the Employee Center.
For the tax payment (from the attached screenshot), QuickBooks is detecting that the Entered Amount is not the same as the Calculated Amount. QuickBooks uses the Wage Base, multiplied by the Rate to generate the amount in the Calculated Amount column. You'll want to reach out to your accountant to verify if this is the correct amount.
