I'm here to help answer your question, @lindabuttle.
Currently, adding a company name when printing cheques is unavailable in QuickBooks Online.
Since we don't have the option to modify the cheque in QBO, you can visit this link for the available pre-printed cheques that can be customised for your business: https://quickbooks.intuit.com/ca/stationery/.
Please don't hesitate to let me know if I can be of further assistance with your transactions or anything else QuickBooks related. I'll be here to help.
