Thanks for joining this thread, DebC-TSB.

When using direct deposit,  there isn't a check number because there's technically no check being deposited. If you make a paper check entry, there will be a section for you to add an appropriate check number.

You'll also be able to find many detailed resources about using QuickBooks in our help article archives.

Please feel welcome to send a reply if there's any questions. Have a great day!
