Hello there, bcriswell.

The File menu can be seen using QuickBooks Desktop. Since you're using QuickBooks Online, you can follow the steps below if you're trying to print vendor checks. Here's how:

2. In the Vendors tab, find and click the vendor's name. 
3. Select Edit at the upper-right corner.
4. On the Print on check as field, make sure to uncheck the Use display name box and enter the company name.
5. Then, click Save. 

Then, open the check and click Print check at the bottom part of the page:

If you're referring to a paycheck, that name is based on the company's information. We can double-check your setting and make sure to add and correct the company information. Here's how:

1. Go to the Gear icon.
2. Select Account and Settings. 
3. In the Company. Click the Company name section. Make sure the company's name is correct.
