Thanks for following along with the thread, @TDean2. 

When we have a rejected echeck in QuickBooks Desktop, you'll need to void it, then recreate a new one using all the same details of the first check. At this time, there isn't a way to resend the same one. I've included some steps below to void the current echeck. 

Here's how: 

1. Sign in to the Merchant Service Center.
2. From the Processing Tools, select Void an eCheck.
3. 
4. Choose the appropriate eCheck to void.
5. Click on Submit to complete the process.

Once you've voided the echeck, you can Create a new one to send. 

For additional details about this process, check out Void an echeck in QuickBooks Desktop. 

Please don't hesitate to let me know if you have any questions or concerns. Have a good one!
