Thanks for posting your question here in the Community, userarlanlitwin.
I'm happy to walk you through the steps to print T4A slips in QuickBooks Online.
You can generate these forms via the Payroll Tax center, where you can review, download, and print them as PDFs for distribution. Here's how to get this done:
Go to Taxes and select Payroll Tax.
Select Annual Forms under the Forms section.
Choose the T4A form type.
Select the relevant tax year.
Click View to open the slips as a PDF in Adobe Acrobat.
Use the print icon within the PDF viewer to print the forms.
