Hi luv2boatnorcal,

Currently, you're unable to edit the check template in QuickBooks. As a workaround, you can check for a third-party app that can print the check in the middle block. 

Also, I'll be sending this to our Product Team to let them know how this is useful to your business. 

I got this link in case you have other questions about QuickBooks: Help Articles.

Post a comment if you have any other concerns. I'm always right here to help.
