I can offer guidance and support in setting the State Unemployment Insurance (SUI) rate for exemption within QuickBooks Online Payroll, iikarynii.
You can input the precise rate you've received as per the documents required by your agency.
Let me show you how.
Go to the Gear icon.
Under YOUR COMPANY, select Payroll Settings.
On the state tax section, select Edit.
Select Change or adda new rate.
Enter the rate and the effective date.
Click OK.
Since you mentioned that QuickBooks Online Payroll doesn't permit you to input or update the Maryland SUI rate, I suggest contacting the Payroll Team to verify that your SUI tax rate is configured correctly.
