Hi there, @tlcconstruction.
Thanks for joining us here in the Community. I'd be happy to provide assistance with having the check number to show up on your register.
In QuickBooks once the you create a check it will be registered on your bank register regardless if its printed or not. You'll need to make sure that you pull up the right account when printing the checks.
I've also included an article about printing checks in QuickBooks Desktop for your future reference: Create, modify, and print checks.
Please let me know how it goes, @tlcconstruction by replying into this thread. I'll be around if you need further help. Have a great day!
