I already updated my payment info. How do II reactivate payroll?

Let me route you to our support so your payroll account gets activated as soon as possible, @jaime17.

I appreciate you for updating your payment information and for following the steps in QuickBooks Online (QBO). 

You're right, you'll need to contact us if you're using QBO Payroll Core, Premium, Elite, and Full Service. Our phone and chat lines are now open. We temporarily suspended support to prevent long hold times as we resolved a direct deposit payroll issue yesterday. Ensure to call them within our support hours to address your concern. For more details, check out this page: Contact Payroll Support.

Once activated, you can always review your payment history by going to the Account and Settings and choose Billing and Subscription tab. 

See the sample screenshot for your reference: 

Feel easy to review this article about handling your subscription, business data, credentials, and other related topics: Account Management. 

Stay in touch with me if you have further questions about your payroll. I'm glad to help you out. Take care always.
