Hello azhar-laldin,
Sometimes it's necessary to check if you're subscribed to payroll and I'll be happy to steer you in the right direction. QuickBooks is an easy to use program which makes it simple to navigate and check your subscriptions.
To check if you're subscribed to payroll, click on the Gear icon > Account and Settings > Billing and Subscriptions > from here you'll see your payroll subscription and other subscriptions. You can also check for other subscriptions such as apps by clicking Apps from your your left navigation menu.
Let me know if this info helps. I'll be here in case you need anything else.
