Let's ensure that the report is still in your register, Gamesnsuch.
When you run the Check Detail report, just make sure that the date range is within the date of the check for it to be included in the report. The check might have also been deleted or voided if you're unable to see it in your register.
You can run the Audit Log report to verify:
Go to the Gear icon and click Audit log.
From the Filter drop-down, enter the date from when you have created the check.
Select the Show only these events option and check Transactions and Lists.
Look for the Check and select View to get the full details.
If the check was mistakenly deleted or voided, you can use the details shown in the audit log in re-entering it and print it from there.
